The present work examined two Pd-based alloys supported on carbon: AuPd and Au2Pd, both synthesized by chemical reduction with NaBH4. The low Au-Pd loading electrocatalysts were physicochemically and electrochemically characterized. Electrocatalytic activity for methanol oxidation was found exclusively in AuPd/C. However, it was revealed that such reaction was promoted by PdO occurring in the actual active phase of the supported electrocatalyst, through the formation of Au-Pd-PdO ensemble sites.

AbstractIn this work, the methanol oxidation reaction is investigated on Ni based metal organic frameworks (MOF) and its composites with biomass derived activated carbon. NiO-MOF and composites with activated carbon were synthesized using hydrothermal method. SEM, EDX, and XRD, FTIR, TGA techniques were used for characterization of composites. The electrochemical activity of catalysts for oxidation of methanol was tested using cyclic voltammetry (CV) in 1 M KOH and 3 M CH3OH on glassy carbon electrode in three electrode setup. The electrochemical performance shows the effect of activated carbon concentration on methanol oxidation. The electro-oxidation catalyzed by NiO-MOF with activated carbon (40 mg) composite exhibits a peak current density of 182.72 mA/cm2 at 0.89 V potential with a scan rate of 50 mV/s making it a potential catalyst for electrocatalysis of methanol.
