Abstract The synthesis of Cu catalysts for hydrazine oxidation has been an important focus study. Herein, nanorod arrays on foam (Cu NRAs/CF) were synthesized. Profiting from its structural characteristics, began at −1.03 V and the current density attained 178.8 mA cm−2 −0.6 V. Compared with CF NPs/CF, NRAs/CF presented a lower charge transfer resistance (Rct) apparent activation energy (Ea), indicating that was associated comparatively fast kinetics.

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.
