Nickel–cobalt alloy doping phosphorus as advanced electrocatalyst for hydrazine oxidation
Journal of Alloys and Compounds(2019)
摘要
Seeking high activity non-noble-metal electrocatalysts is essential to develop high performance hydrazine fuel cells. In this study, an electrocatalyst of phosphorus doped nickel-cobalt alloy is fabricated for hydrazine oxidation reaction (HzOR). A series of physical and electrochemistry results show that, among as-prepared four electrocatalysts, the NiCoP/C has the lowest Tafel slope, the highest current density, the longest durability and relative low apparent activation energy for HzOR. Moreover, the influences of KOH and N2H4 concentrations, scanning speeds as well as the temperatures as to NiCoP/C electrocatalyst towards HzOR are also investigated. Besides, electrochemical impedance test exhibits as-obtained NiCoP/C owes good charge transfer kinetics. This work would stimulate more study to explore P doped non-noble metal electrocatalyst in the future.
