摘要: Carbon-supported Au-doped N-C-coated CoFe alloy nanocomposite electrocatalysts (Au/CoFe@CN/C) are prepared and applied to BH4− electrooxidation. The physical electrochemical properties of the catalysts characterized tested by X-ray diffraction, transmission electron microscopy, cyclic voltammetry, chronamperometry, chronopotentiometry, rotating disk electrode voltammetry. results show that Au(50)/CoFe@CN(50)/C has excellent catalytic performance for electrooxidation, high charge transfer number up 6.4, low precious metal content, making it a promising anode electrocatalyst direct borohydride fuel cell.
