Catalysts, Год журнала: 2025, Номер 15(4), С. 400 - 400

Опубликована: Апрель 19, 2025

In this study we present an application of wood biomass—alder char—as the carbon precursor for synthesis novel and sustainable nitrogen-doped activated-carbon-supported nickel nanoparticle catalyst (AWC-Ni-N) hydrazine oxidation. For comparison, wood-based material doped with nitrogen only (AWC-N) was also synthesized. Extensive characterization, including SEM, Raman spectroscopy, XPS, XRD revealed catalysts’ microstructure properties. Electrochemical testing demonstrated that AWC-Ni-N significantly enhanced efficiency oxidation reaction. addition, direct N2H4-H2O2 single-fuel-cell tests were conducted using prepared AWC-N catalysts as anodes cathodes. Peak power densities up to 10.8 mW cm−2 achieved at 25 °C, corresponding a current density 27 mA cell voltage 0.4 V when used both anode cathode. Furthermore, peak increased by approximately 1.6 2.9 times, respectively, operating temperature raised from °C 55 catalysts. Overall, significant potential cathode materials in fuel cells.

Опубликована: Апрель 26, 2025

Abstract The electrocatalytic oxidation of benzyl alcohol (BAOR) is crucial for promoting green industrial processes and enhancing the yield productivity high‐value chemicals. However, there are challenges in this field, such as difficult steps alkaline electrolytes, slow reaction kinetics, difficulty preserving activity catalysts during long‐term catalytic reactions. Addressing these issues achieving synergistic reactions to improve energy utilization by combining hydrogen evolution with enhanced catalyst stability warrants focused investigation. Herein, study reports a Co 3 Ni 6 S 8 ‐based catalyst, 0.33 0.67 1 ‐10c, which can achieve (BA) solution over 350 h, conversion rate BA exceeding 90% Faraday efficiency benzoic acid (BAA) 99%. production capacity ‐10c also evaluated both three‐electrode dual‐electrode systems. In system, factor 9.59 compared absence BA, while increased 7.85. This work presents highly efficient durable its integration production.
