Abstract :

Single-atom catalysts (SACs) have attracted intensive attention due to their highest atom utilization, especially for expensive noble metal catalysts. This article provides a comprehensive review of defect engineering in the preparation of SACs. A unique view of the synergy of single atoms and defects during biomass conversion reactions is presented. The role of defects on SACs in biomass conversion reactions is discussed. The adsorption activation mechanism, local promotion mechanism, active site renewal mechanism, and selective recognition mechanism of defects are proposed and explained. Through the classification and in-depth analysis of typical biomass conversion reactions using SACs, the promising potential of defect engineering in broader biomass upgrading is illustrated. It is hoped that this paper provides guidance for the rational design of SACs and their application in a wide range of systematic biomass conversions.

Investigation on catalytic distillation dehydrogenation of perhydro-benzyltoluene: Reaction kinetics, modeling and process analysis SCIE
期刊论文 | 2024 , 482 | CHEMICAL ENGINEERING JOURNAL
Abstract&Keyword Cite

Abstract :

Catalytic distillation is an effective and important technology for low-temperature dehydrogenation of perhydrobenzyltoluene (H12-BT). However, current researches have unfortunately failed to comprehensively understand the reaction and separation processes, hindering the broader application of catalytic distillation dehydrogenation technology. Therefore, in the study, a comprehensive dehydrogenation reaction kinetic model that accounts for the influence of the intermediate H6-BT was established firstly. Subsequently, the vapor-liquid equilibrium data for the binary systems H12-BT + H6-BT and H6-BT + H0-BT was estimated by utilizing the UNIFAC model, so as to obtain the azeotropes. By developing a modified catalytic distillation model, the catalytic distillation dehydrogenation process was examined. Our exploration revealed the existence of an optimal degree of dehydrogenation value, namely 0.8, within the catalytic distillation dehydrogenation process, yielding an approximate 23.8 % reduction in unit H2 production cost in comparison to the fully dehydrogenation case. Our findings contribute valuable insights that have the potential to promote the overall development of the hydrogen energy economy.

Catalytic hydrotreatment of fast pyrolysis liquids from Pine wood using Ru-based catalysts supported on nitrogen-doped carbon materials SCIE
期刊论文 | 2024 , 368 | FUEL
Abstract&Keyword Cite

Abstract :

Catalytic hydrotreatment is one of the promising routes for upgrading pyrolysis liquids (PLs) to intermediates that can be co-fed with vacuum gas oil for FCC refinery. Among all the factors, catalysts are always crucial in catalytic hydrotreatment of PLs as hydrogenation and repolymerization reactions occur in parallel. Therefore, catalysts with sufficient hydrogenation activity are generally required to enhance the hydrogenation reaction and to inhibit the repolymerization reaction of the thermally liable compounds in PLs. Among all noble metal catalysts tested, Ru/C catalysts showed a better performance than other catalysts in terms of the oil yield and deoxygenation level. However, a clear repolymerization was observed during catalytic hydrotreatment of PLs using Ru/C catalysts, especially during mild hydrotreatment, thus there is still ample room for their activity improvement. Here, a series of Ru-based catalysts supported on nitrogen-doped carbon materials (NC) and activated carbon (AC) were prepared. The catalytic performance was evaluated for hydrotreatment of PLs in a batch autoclave (250 degrees C, 8 MPa H2, 4 h for mild hydrotreatment; 340 degrees C, 6 MPa H2, 4 h for deep hydrotreatment). The Ru catalyst supported on nitrogen-doped carbon materials, obtained by the polyol reduction method with polyvinylpyrrolidone (PVP) as the protective agent (Ru/NC (PVP)), showed a better performance (in terms of product oil properties) than the other catalysts investigated in this work, due to a good distribution of the ruthenium nanoparticles. For mild hydrotreatment the H/C ratio, O/C ratio and MCRT value were 1.42, 0.37 and 9.9 wt%, respectively. For deep hydrotreatment the H/C ratio, O/C ratio and MCRT value were 1.26, 0.16 and 4.6 wt%. The comparison with results published earlier for other hydrotreatment catalysts is satisfactory but also shows room for further improvement. GC-MS and 1H NMR results showed that the contents of thermal liable components like aldehydes (16.7 %), ketones (24.3 %) and sugars (4.0 %) in PLs were quantitatively converted under mild hydrotreatment, while phenols and alkanes significantly increased from 35.9 %, 0 % to 49.1 %, 35.3 %, respectively, especially for deep hydrotreatment compared with PLs feed. The catalyst characterization revealed that Ru/NC (PVP) with the most uniform dispersion and the smallest average particle size (1.5 nm), rendered the best performance. These findings indicate that Ru/NC (PVP) catalyst is a promising candidate for the catalytic hydrotreatment of PLs.

Water management and performance enhancement in proton exchange membrane fuel cell through metal foam flow field with hierarchical pore structure EI
期刊论文 | 2024 , 494 | Chemical Engineering Journal
Abstract&Keyword Cite

Abstract :

Compressing metal foam flow field usually causes a higher pressure drop and uncontrollable pore structure while enhancing the water discharge capability of proton exchange membrane fuel cell (PEMFC). To further enhance the water discharge capability of metal foam flow field at a low cost of pressure drop, a novel metal foam flow field exhibiting hierarchical pore structure(dcoarse/dfine=2; Vcoarse/Vfine=1; dfine=0.5 mm) is first introduced. This work numerically investigates water management characteristics and output performance of novel metal foam flow field. Subsequently, 3D printing technology is employed to precisely manufacture metal foam flow fields, which are compared with several flow fields in the cathode side experimentally. Experimental results demonstrate that at 1.5 A/cm2 during 3 h, the amount of water discharge in metal foam flow field with hierarchical pore structure is close to parallel flow field, which is 1.12 times and 1.30 times that in metal foam flow field with uniform coarse pore and uniform fine pore, respectively. Moreover, compared with the previous optimized strategy, namely metal foam flow field with 75 PPI and a compression rate of 0.75, metal foam flow field with hierarchical pore structure can not only improve the maximum net power density by 9.5 % and water discharge amount by 14.1 %, but also decrease two-thirds of the pressure drop in the cathode side. This research lays the theoretical groundwork and offers technical insight for the implementation of metal foam flow fields in PEMFCs. © 2024 Elsevier B.V.

Layered carbon encapsulated CuOx nanopaticles for selective hydrogenation of furfural to furfuryl alcohol EI
期刊论文 | 2024 , 565 | Molecular Catalysis
Abstract&Keyword Cite

Abstract :

Furfuryl alcohol (FOL) is commercially available by selective hydrogenation of furfural (FAL). A variety of catalysts have been developed for such purpose, among which Cu-based catalysts show superior catalytic performance. However, copper nanoparticles with complex valence states are easy to agglomerate during hydrogenation reaction, which might have a negative influence on the catalytic performance. The carbon coating is an efficient strategy to prevent the sintering of Cu-based catalysts. Herein, a strategy based on the thermal decomposition of Cu-EDTA complex was designed to prepare carbon encapsulated Cu-based catalysts. The prepared catalysts were applied in the selective hydrogenation of FAL to FOL in the batch reactor. The results showed that a nearly quantitative conversion of FAL with a selectivity of 98.7 % towards FOL was achieved using CuOx@NC-150 (molar ratio of Cu: Na4EDTA·4H2O=2:1; obtained by oxidative activation at 150 °C) under 140 °C, 3 MPa in 4 h. The performance was comparable to that of the commercial CuCr2O4 catalyst under the identical conditions. In addition, the developed carbon encapsulated Cu-based catalysts exhibited a slightly better stability than CuCr2O4 catalyst in terms of FOL yield in five consecutive cycles. XPS and XAES characterizations implied that the presence of a suitable surface ratio of Cu+/(Cu++Cu0) of the prepared catalyst may contribute to the selective hydrogenation of FAL to FOL. © 2024 Elsevier B.V.

Abstract&Keyword Cite

Abstract :

The balance between water discharge and mass transfer within metal foam flow field is vital for elevating the performance of proton exchange membrane fuel cell (PEMFC). To obtain an improved balance, this work designs a novel bilayer structure with two types of PPI (pore per inch) for metal foam flow field. Experimental and numerical results confirmed that arranging a metal foam featuring a smaller PPI in the layer 1 near the membrane electrode assembly (MEA) and a larger PPI in the layer 2 away from the MEA is beneficial to enhance the output performance. The excellent PPI combination for balancing mass transfer and water discharge involves utilizing a 50 PPI metal foam for the layer 1 and 110 PPI metal foam for the layer 2. Compared to conventional metal foam with 50 PPI, metal foam flow field with excellent PPI combination showcases a 11.2 % increase in water discharge and a 13.2 % boost in mass transfer, leading to a notable 23.5 % performance enhancement. Similarly, compared to conventional metal foam with 110 PPI, there is a 7.3 % decrease in mass transfer but a significant 29.5 % increases in water discharge, leading to a 15.2 % performance improvement. © 2024 Elsevier Ltd

Two-step synthesis of coconut shell biochar-based ternary composite to efficiently remove organic pollutants by photocatalytic degradation SCIE
期刊论文 | 2024 , 12 (3) | JOURNAL OF ENVIRONMENTAL CHEMICAL ENGINEERING
Abstract&Keyword Cite

Abstract :

Designing environmentally friendly, low cost and efficient photocatalysts is vitally important for degradation of organic pollutants. Herein, a ternary composite-ZnO/ACSC@TiO2, constituted by activated coconut shell derived biochar (ACSC), TiO2 and ZnO, was successfully synthesized by two-step hydrothermal method. It demonstrated that TiO2 could be uniformly wrapped on ACSC surface during first step to form core-shell structures (ACSC@TiO2). It was beneficial not only to enhance adsorption capacity for organic pollutants and absorption ability for light, but also to form C-doped TiO2 with a relatively narrow bandgap to expand light absorption of TiO2 from UV to visible light. Subsequently, ZnO was introduced through second step to generate type-II heterojunctions with ACSC@TiO2, which further reduced bandgap value of the ternary photocatalyst to promote photogenerated carrier generation and efficiently diminished recombination of e--h+ pairs. As expected, the optimal prepared catalyst with 10 wt% of ZnO (10%ZnO/ACSC@TiO2) exhibited excellent adsorptive and photocatalytic abilities for removal of tetracycline (TC) and Rhodamine B (RhB) with different initial concentrations. Particularly, its total removal efficiency for TC and RhB was 97.6% and 99.4%, respectively under 300 W xenon lamp irradiation (25 mg/L of organic pollutants, 1.0 g/L catalyst and natural pH in 60 min). Investigations on catalytic mechanism and degradation pathways proved that 10%ZnO/ACSC@TiO2 could remove RhB and TC by deep degradation. Its enhanced synergy of adsorption and photocatalysis could efficiently accelerate mineralization rates of RhB and TC. This biomass derived biochar-based ternary composite as photocatalyst with optimized energy band structures and microstructures would have good industrial application potential.

Abstract :

A bimetallic PtNi-vinyl complex as catalytic active center was created on modified rice straw biochar by introducing an appropriate amount of cheap Ni component as a catalytic promoter. The constructed bimetallic catalyst (PtNi-VTES-RSOC) was used to catalyze hydrosilylation of terminal alkenes with tertiary silanes to produce alkylsilanes with high commercial application value. The experimental results proved that the conversion of 1-octene 96.5 % and selectivity for target product 97.1 % were obtained in hydrosilylation of 1-octene with triethoxysilane catalyzed by PtNi-VTES-RSOC with mass ratio of Pt/Ni = 1.5:1 (molar ratio of Pt/Ni approximate to 1:2) under mild conditions (atmospheric pressure, solvent-free, 50 degree celsius and 3 h). It also possessed higher catalytic ability and regioselectivity for hydrosilyation of long-chain alkenes (1-octadecene) with tertiary silanes compared to the counterpart monometallic catalysts. The characterization and theoretical calculation results demonstrated that the introduced suitable amount of Ni(II) could affect the structure of original Pt(II)-vinyl complexes and form a stable and unique bimetallic vinyl coordination microstructure by using a shared vinyl group, thereby affecting morphology, structure, and catalytic performance of the as-prepared bimetallic catalyst with mass ratio of Pt/Ni = 1.5:1. Changing the introduction order and introducing excessive or insufficient of Ni (II) would both disrupt the formation of this special structure and affect the catalytic performance. Additionally, the formed stable complex structure with vinyl groups could well maintain the catalytic stability. The study results exposed that the as-prepared bimetallic catalyst would possess a great industrial application potential in the hydrosilylation of alkenes by efficiently increasing the product quality and reducing operation cost.

Fabrication of a corn stalk derived cellulose-based bio-adsorbent to remove Congo red from wastewater: Investigation on its ultra-high adsorption performance and mechanism SCIE

Abstract&Keyword Cite

Abstract :

A cellulose-based bio-absorbent with various and plenty of amino groups was successfully prepared from corn stalk to achieve quantitative removal of Congo red from wastewater with wide pH values (5 <= pH <= 10). The maximum removal amount was 8.0 mmol center dot g(-1) (5572 mg center dot g(-1)) under pH = 6.0 and 45 degrees C, which was obviously higher than reported absorbents. Investigation on dynamic adsorption and recyclability in authentic wastewater found that the removal efficiency of Congo red was >98 % within 180 min and decreased slightly in industrial water after five cycles, denoting this adsorbent with great potential for environmental application. The characterization results proved that 7.58 mmol center dot g(-1) of different amino groups (-NH2, -NH- and -NR2) were introduced on adsorbent surface by two steps of modification and were the major functional groups for adsorption of Congo red. The inferred adsorption mechanism revealed that Congo red could be adsorbed equivalently on the amino groups by strong electrostatic interactions or hydrogen bonds. Different amino groups played different roles in adsorption due to great differences in protonation ability in 5 <= pH <= 10. The study was expected to highefficiently remove Congo red from acidic or alkaline wastewater, and offered an alternative strategy for biowaste treatment of corn stalks in a high value-added manner.

Abstract&Keyword Cite

Abstract :

Alkylsilanes, obtained from hydrosilylation of alkenes with tertiary silane, have high commercial application value. It is crucial to develop a heterogeneous Pt-based catalyst with high activity and high regioselectivity to catalyze this hydrosilylation reaction under solvent-free and mild conditions. Herein, a stable Pt(II)-vinyl complex with unique structure was successfully constructed on oxidized rice straw biochar through reasonable structural design and modification steps. Pt particles on the as-prepared catalyst (Pt-VTES-RSOC) were evenly dispersed with relatively minimum particle sizes (0.3 similar to 2.5 nm). Compared to classic homogeneous catalysts, Pt-VTES-RSOC showed superior activity, great regioselectivity for tertiary silanes and high reusability. The apparent kinetic models for representative reactions over Pt-VTES-RSOC were also proposed to simulate the catalytic process under suggested reaction conditions for clarifying the reaction mechanism. The study proved that Pt-VTES-RSOC would have a good industrial application potential in hydrosilylation of alkenes with tertiary silanes by reducing operation cost and increasing the product quality.
