Abstract :

Developing efficient anode catalysts for direct ammonia solid oxide fuel cells (NH3-SOFCs) under intermediate-temperatures is of great importance, in support of hydrogen economy via ammonia utilization. In the present work, the pyrochlore-type La2Zr2-xNixO7+delta (LZN(x), x = 0, 0.02, 0.05, 0.08, 0.10) oxides were synthesized as potential anode catalysts of NH3-SOFCs due to the abundant Frankel defect that contributes to the good conductivity and oxygen ion mobility capacity. The effects of different content of Ni2+ doping on the crystal structure, surface morphology, thermal matching with YSZ (Yttria-stabilized zirconia), conductivity, and electrochemical performance of pyrochlore oxides were examined using different characterization techniques. The findings indicate that the LZN(x) oxide behaves as an n-type semiconductor and exhibits an excellent high-temperature chemical compatibility and thermal matching with the YSZ electrolyte. Furthermore, LZN(0.05) exhibits the smallest conductive band potential and bandgap, making it have a higher power density as anode material for NH3-SOFCs compared to other anodes. As a result, the maximum power density of the LZN(0.05)-40YSZ composite anode reaches 100.86 mW/cm(2) at 800 degrees C, which is 1.8 times greater than that of NiO-based NH3-SOFCs (56.75 mW/cm(2)) under identical flow rate and temperature conditions. The extended durability indicates that the NH3-SOFCs utilizing the LZN(0.05)-40YSZ composite anode exhibits a negligible voltage degradation following uninterrupted operation at 800 degrees C for 100 h.

Abstract :

Ammonia decomposition for onsite hydrogen production has been regarded as an important reaction which links to efficient hydrogen storage, transport and utilization. However, it still remains challenging to develop efficient catalysts with robust stability for ammonia decomposition. Herein, an integrated strategy was employed to synthesize Ru/SiO2@N-CS via wrapping a thin layer of N-doped carbon onto the SiO2 sphere, following the anchor of Ru nanoparticles (NPs) onto the support. The obtained Ru/SiO2@N-CS (Ru loading: 1 wt%) shows a promising performance for ammonia decomposition, reaching 94.5 % at 550 °C with a gas hourly space velocity (GHSV) of 30 000 mL gcat-1h−1. The combination of the SiO2 as the core prevents the degradation of N-doped carbon layers and then enhance the durability of the catalysts, remaining stable after 50 h at evaluated temperatures. Adequate characterizations were used to illustrate the effect of microchemical environment on ammonia decomposition activity of Ru/SiO2@N-CS catalyst under different calcination atmosphere and the correlation between structure and performance. © 2024 Elsevier B.V.

Abstract :

The design of novel practical catalysts is critical for the blossoming of biodiesel green-energy, in which Mo-based catalysts are of particular interest. In this work, an in-situ synthesis method was proposed to obtain a combo Mo-based ionic liquid and SAPO-11 catalyst. The catalyst presents both highly dispersed MoS2 as hydrodeoxygenation active sites and acidic sites for isomerization. MoS2 with a few fine layers can be identified based on TEM images and the Bronsted acid sites are dominant based on Pyridine-IR analysis. A great performance of MoS2/C(8)min-15 %SA can be obtained under optimized reaction conditions with 100 % conversion of methyl palmitate, 75.0 mol% hydrodeoxygenation to n-C-15-C-16, and 20.5 mol % isomerization to i-C-15-C-16. The structure and activity of the catalyst can be retained at least for 4 cycles. Thin layers and high sulfurization, large amount of Br & oslash;nsted acid sites, and suitable reaction conditions are key points to achieve a significant performance and avoid over cracking and deactivation. On basis of detected intermediates and kinetic data simulations, a complex reaction pathway was proposed and the specific k values for each elementary reaction were provided for the hydrodeoxygenation and isomerization of methyl palmitate.

Abstract :

Ammonia (NH3) is closely related to the fields of food and energy that humans depend on. The exploitation of advanced catalysts for NH3 synthesis has been a research hotspot for more than one hundred years. Previous studies have shown that the Ru B5 sites (step sites on the Ru (0001) surface uniquely arranged with five Ru atoms) and Fe C7 sites (iron atoms with seven nearest neighbors) over nanoparticle catalysts are highly reactive for N2-to-NH3 conversion. In recent years, single-atom and cluster catalysts, where the B5 sites and C7 sites are absent, have emerged as promising catalysts for efficient NH3 synthesis. In this review, we focus on the recent advances in single-atom and cluster catalysts, including single-atom catalysts (SACs), single-cluster catalysts (SCCs), and bimetallic-cluster catalysts (BCCs), for thermocatalytic NH3 synthesis at mild conditions. In addition, we discussed and summarized the unique structural properties and reaction performance as well as reaction mechanisms over single-atom and cluster catalysts in comparison with traditional nanoparticle catalysts. Finally, the challenges and prospects in the rational design of efficient single-atom and cluster catalysts for NH3 synthesis were provided. Recent advances in single-atom and cluster catalysts, including single-atom catalysts (SACs), single-cluster catalysts (SCCs), and bimetallic-cluster catalysts (BCCs), for thermocatalytic NH3 synthesis at mild conditions.

Abstract :

The capture the low-content NH3 from industrial streams, and recycle it as the feedstocks for industrial processes is very important. In this work, we reported the use of mesoporous polydivinylbenzene (PDVB) as the support of metal-based deep eutectic solvents (DESs) containing choline chloride (ChCl) and metal chlorides (SnCl2, FeCl3 or ZnCl2) for NH3 capture. The structure of composite materials was characterized in details, and the NH3 capture performance and mechanism of them were also examined in depth. Owing to the coordination interaction of metal ions with NH3, along with the hydrogen-bond interaction of - OH and Cl- with NH3, the DES@PDVB composites exhibit considerably high low-content NH3 capacities. The optimized sample ChCl + 2ZnCl2@PDVB1.5 can adsorb 7.43 mol/kg of NH3 at 25 degree celsius and 0.122 bar, which is advantageous over most other adsorbents fabricated in the literature. The mechanism of NH3 capture by DES@PDVB composites was also illustrated through spectroscopic characterizations.

Abstract :

The use of bio-oil-based polymers in fertilizer coatings has drawn significant academic interest. However, the challenge remains to eliminate toxic chemicals while enhancing comprehensive properties. This study focused on synthesizing a degradable polymer from epoxidized soybean oil (ESO) without organic solvent at low temperature (120°C), accomplished through a modified curing agent (MCA). This MCA was made of an acidic eutectic mixture of phthalic anhydride (PA) and its glycerides, produced from inexpensive, low-toxic phthalic anhydride and glycerol. The process utilized a small quantity of zinc acetate (0.5 wt%) to facilitate the formation of phthalic triglyceride in the MCA and mitigate PA sublimation, resulting in the enhanced cross-link degree, superior mechanical properties and hydrophobicity of the ESO-based resin (ESOR). Under optimal preparation conditions, the solvent-free ESOR-coated fertilizer exhibited an extended longevity of 53 days, with an 80 % phosphorus release. This coating material can undergo hydrolytic degradation in soil and in-situ conversion into carboxylates. These findings hold significant potential for advancing the applications of ESOR in green and sustainable agriculture. © 2024 Elsevier B.V.

Abstract :

gamma-ray radiation-induced grafting strategy was first employed to immobilize 4-aminobenzo-15-crown-5 onto a covalent organic framework (COF). This endeavor culminated in the successful synthesis of a class of two-dimensional crown ether-modified COFs (named [15C5]n%-(TzDa-G-x%)), marking the maiden utilization of COFs in the realm of 6Li/7Li isotope separation. These COFs exhibited swifter adsorption kinetics than alternative adsorbents. Among them, [15C5]57%-(TzDa-G-50%) with its excellent crystallinity, porosity, and stability exhibited the best performance in Li+ adsorption and 6Li/7Li isotope separation. The Li+ adsorption in acetonitrile achieved a capacity of 3.6 mg center dot g-1 within 30 min and a saturation capacity of 7.3 mg center dot g-1. The single -stage separation factor of 6Li/7Li isotopes was 1.014 +/- 0.001. The results of dynamic adsorption column experiments showed that the packed column made of [15C5]57%-(TzDa-G-50%) maintained stable performance during four cycles of Li+ adsorptionelution, with over 99% Li+ removal rate in acetonitrile. This crown ether-modified COF has potential application in 6Li/7Li isotope separation, and this radiation-assisted synthesis strategy is expected to become universal in the modification of COFs for diverse applications.

Abstract :

A series of mesoporous polymers functionalized with different kinds and contents of Br & oslash; nsted acidic sites were designed and synthesized for NH 3 capture. The textural properties, morphologies and chemical structures of synthesized mesoporous polymers were characterized in details, and the NH 3 capture performance was evaluated systematically. It is found that the mesoporous polymers functionalized with phosphoric sites exhibit much better NH 3 capture performance at low pressures than those with carboxylic and sulfonic sites. Specifically, the NH 3 adsorption capacities of P(DVB-VPA)-4.0 can reach 4.82 mmol/g at 298.2 K and 0.033 bar. The excellent ability of P(DVB-VPA)-4.0 for selectively adsorbing low -content NH 3 from NH 3 /N 2 /H 2 and NH 3 /N 2 /CO 2 mixed gases was demonstrated by breakthrough experiments, and the adsorption of NH 3 by P(DVB-VPA)-4.0 is found to be mostly reversible. The thermodynamic properties and mechanism of NH 3 adsorption were also examined in depth, disclosing the important role of Br & oslash; nsted acidic sites in enhanced capture of low -content NH 3 by P(DVBVPA)-4.0.
