Abstract

Nano-scale Ni(OH)₂ doped Co was prepared by precipitate transformation method, and the effect of the percentage of doped Co on the performance of material was investigated. The measurement results of XRD and TEM indicate that nano-scale β-Ni(OH)₂ doped different percentage of Co can be prepared by precipitate transformation method, with the increase of the percentage of doped Co, the crystal lattice defect increases obviously, lattice parameters and surface state have changed correspondingly also. The study of cyclic voltammetry (CV) behavior used a microelectrode shows that the CV performance of nano-scale Ni(OH)₂ doped Co is enhanced, and the percentage of doped Co can exert a great influence on the peak potential (E_p,a and E_p,c) and proton diffusion coefficient (D), the material doped 5% Co exhibits relative superior CV performance.
