Abstract :

Electrochemical biomass upgrading is a promising substitute for oxygen evolution reaction (OER) to generate valuable chemicals in conjunction with hydrogen generation. Pursuing highly efficient and durable electrocatalysts for significant concentration levels (≥ 50 mM) of biomass electrooxidation remains an enduring challenge. Herein, we introduce a robust Cu-supported CoFe Prussian blue analogue (CoFe PBA/CF) electrocatalyst, adept at facilitating high-concentration (50 mM) 5-hydroxymethylfurfural (HMF) oxidation into 2,5-furandicarboxylic acid (FDCA), achieving an exceptional HMF conversion (100%) with a notable FDCA yield of 98.4%. The influence of copper substrate and adsorption energy are therefore discussed. Impressively, the CoFe PBA/CF electrode sustains considerable durability in a continuous-flow electrochemical reactor designed for consecutive FDCA production, showcasing FDCA yields of 100/94% at flow rates of 0.4/0.8 mL·min-1 over 60 h’ uninterrupted electrolysis. This work provides a promising strategy to develop highly efficient and robust electrocatalysts for the consecutive production of high-value products coupled with green H2 production. © The Author(s) 2025.

Solvent-free deoxygenation of biolipid into liquid alkanes over bifunctional Ni/B2O3-ZrO2 catalyst SCIE

Abstract&Keyword Cite Version(2)

Abstract :

The efficient deoxygenation of renewable biolipids into liquid alkanes within the diesel range is a key protocol for producing high-quality biofuels. In this work, the conversion of methyl palmitate and raw palm oil were accomplished utilizing a bifunctional catalyst of Ni catalysts supported on B2O3-ZrO2 under solvent-free conditions. Among various Ni loading ratios investigated, the catalyst featuring a 10 % Ni loading achieved 100 % conversion of methyl palmitate and 84.4 % of liquid yield, with approximately 65 % being C15 alkanes. Additionally, more than 91 % of hydrocarbons were also generated from raw palm oil. These results can be attributed to the synergistic interplay between the acid sites, following B2O3 modification, and the presence of Ni species. Furthermore, the analysis of product distribution, gas product detection and the kinetics calculation strongly supports that the deoxygenation process of methyl palmitate primarily follows the hydrodecarbonylation route, leading to the predominant formation of C15 alkane.

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 :

Electrocatalytic nitrate reduction reaction (NO3RR) has been capturing immense interest in the industrial application of ammonia synthesis, and it involves complex reaction routes accompanied by multi-electron transfer, thus causing a challenge to achieve high efficiency for catalysts. Herein, we customized the Cu-O-Ti-Ov (oxygen vacancy) structure on the Cu/TiO2 catalyst, identified through density functional theory (DFT) calculations as the synergic active site for NO3RR. It is found that Cu-O-Ti-Ov site facilitates the adsorption/association of NOx- and promotes the hydrogenation of NO3- to NH3 via adsorbed *H species. This effectively suppresses the competing hydrogen evolution reaction (HER) and exhibits a lower reaction energy barrier for NO3RR, with the reaction pathways: NO3* -> NO2* -> HONO* -> NO* -> *NOH -> *N -> *NH -> *NH2 -> *NH3 -> NH3. The optimized Cu/TiO2 catalyst with rich Cu-O-Ti-Ov sites achieves an NH3 yield rate of 3046.5 mu g h-1 mgcat-1 at -1.0 V vs. RHE, outperforming most of the reported activities. Furthermore, the construction of Cu-O-Ti-Ov sites significantly mitigates the leaching of Cu species, enhancing the stability of the Cu/TiO2 catalyst. Additionally, a mechanistic study, using in situ characterizations and various comparative experiments, further confirms the strong synergy between Cu, Ti, and Ov sites, which is consistent with previous DFT calculations. This study provides a new strategy for designing efficient and stable electrocatalysts in the field of ammonia synthesis. Published by Elsevier B.V. All rights reserved.

Abstract :

Electrocatalytic oxidation as a promising route to produce value-added products from biomass-derived organics has received increasing attention in recent years. However, the efficient conversion of concentrated feedstock solutions with high selectivity and Faradaic efficiency (FE) remains challenging. Herein, we report a cation-defective Ni-based electrocatalyst derived from the surface reconstruction of the NiCo Prussian blue analogue (NiCo PBA) in alkaline media for the efficient oxidation of biomass-derived organics in a high concentration solution. Taking 5-hydroxymethylfurfural (HMF) as an example, the NiCo PBA can deliver a satisfactory catalytic performance in terms of high HMF conversion (97%), selectivity to 2,5-furandicarboxylic acid (98%), and FE (100%), even at a concentration as high as 100 mM. Theoretical calculations suggest that the cation defects not only promote the fast conversion of Ni(OH)(2) to electrochemically active NiOOH under anodic potential but also enhance the adsorption of HMF onto the active sites and accelerate the spontaneous chemical oxidation. This study provides deep insights into the structural evolution of PBA-based catalysts and reveals the pivotal factor that affects the performance of electrocatalytic oxidation, paving the way to further develop advanced electrocatalysts for efficient oxidation reactions with a high concentration.

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.

Mechanochemistry-based liquid-assisted synthesis of hydrophobic Zr-Beta with high metal loading for Meerwein-Ponndorf-Verley reduction SCIE

Abstract :

Heteroatom-incorporated zeolite catalysts are critical for biomass utilization and feedstock valorization in green chemistry. Key features are adjustable acidity, high stability, and a tailored range of functionalities. However, an environmentally benign synthesis of zeolites with good crystallinity and especially with high levels of metal substitution into the lattice remains challenging. Here, we propose a mechanochemistry-based liquid-assisted method (MCLA) for Zr-incorporated Beta zeolites that is high yielding, facile and sustainable. Compared with the fluoride-mediated hydrothermal method, crystallization times were considerably shortened so that Si-Beta and Zr-Beta (Si/Zr 100) zeolites can be synthesized within 9 and 15 h, respectively. Using the MCLA route, Beta zeolites with Zr loading up to 10.4 wt% (Si/Zr 12.5) were obtained. The materials have excellent catalytic activity for Meerwein-Ponndorf-Verley reductions with much higher water tolerance compared to Zr-Beta prepared by the post-synthesis method. The hydrophobic nature of the MCLA-synthesized zeolites makes them particularly useful as catalysts for organic reactions.

Abstract :

Heterogeneous hydrogenation is an effective way to improve the performance of unsaturated polymers, but the preparation of supported catalysts with high metal dispersion and stability remains challenging. Herein, we synthesize a SiO2-based support wrapping with carbon nitride on the surface (CNx@SiO2) via the thermal polycondensation of melamine, on which Pd nanoclusters with highly exposed active sites are formed and stably anchored via the strong interaction between N and Pd. The thermal temperature affects the properties of CNx, which further modulates the electronic and structural state of Pd nanoclusters. The Pd/CNx @SiO2-500 catalyst, prepared at 500 degrees C with an optimal CNx structure (g-C3N4) and high nitrogen content, features highly dispersed and electron-rich Pd nanoclusters (1.3 nm). This catalyst exhibits a hydrogenation activity of 98.0% for nitrile rubber, with a selectivity of 100% for C=C bonds. This work provides a facile method to prepare Pd catalysts with high activity and stability, paving the way for the upgrading of unsaturated polymers via hydrogenation.

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 electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) represents a promising pathway for producing biomass-derived value-added chemicals. Nevertheless, the use of extremely expensive ion exchange membranes (IEMs) as separators significantly sacrifices the economic benefit in large-scale applications. Herein, we report a cost-effective non-fluorine cation exchange membrane (CEM) by grafting sulfonic acid (-SO3- ) groups onto the aromatic side chain of the polyethersulfone (PES) polymer. By tuning the content of -SO3 - groups, the physicochemical properties of the resulting CEMs can be easily adjusted. Impressively, the optimal HBS-PES-1.0 CEM with fully grafted -SO3- groups can achieve a high HMF conversion of 100 %, FDCA selectivity of 98.0 %, and Faradaic efficiency of 98.3 % when used as the separator for electrocatalytic oxidation of HMF, surpassing that of the commercial Nafion 117 membrane (100 % HMF conversion, 98.1 % FDCA selectivity, and 97.4 % Faradaic efficiency). This study provides a cost-effective and high-performance CEM as a substitute for the expensive commercial membrane, paving the way to large-scale commercial applications of biomass upgrading through the electrolysis process.
