Abstract:
Ni-B amorphous alloy particle is a newly promising candidate of catalyst for methanol electrooxidation in Direct Methanol Fuel Cell (DMFC). For enhancing catalytic activity and increasing surface area, mesoporous Ni-B amorphous alloy nanoparticles was manufactured by chemical reduction of NiCl 2 and KBH 4 via surfactant hexadecyltrimethyl ammonium bromide (CTAB) as an soft template. The effects of the CTAB content and the feeding order on the phase evolution, microstructure, and surface area of the resulting products were investigated. Phase and structure of the samples were investigated using XRD, SEM and BET. Amorphous Ni-B nanoparticles with mesoporous structure were obtained in this study. The CTAB content great impacted the mesoporous structure of the resulting products, although the obviously effect on the phase was not found. The surface area, pore volume and pore diameter of samples improved with the increase of CTAB content. Compared to nanoparticles obtained by CTAB solution added to NiCl 2 solution, nanoparticles obtained by NiCl 2 solution added to CTAB solution exhibited better mesoporous structure.
