Abstract:
The carbon- supported Pt- Au b im eta llic nanopa rtic le electrocata ly st w as prepa red v ia a carbony l route. Xray d iffraction and TEM characteriza tions o f the cata lysts showed that the as-prepa red Pt- Au /C ca talyst has a sm a ll partic le sizew ith a re la tive ly narrow size d istribution and re la tive ly low cry sta llin ity. The mean particle size of the Pt- Au / C cata ly st after heat treatm ent at 600 ℃ is only slightly larger than that of the as-prepared ca talyst, indica ting that the Pt - Au bim eta llic cata lyst exh ibits a good therm al stab ility. In compar ison to the comm e rc ia lly av ailable Pt/C ca talyst from E- Tek, the b im eta llic Pt- Au cata lyst exh ibits an enhanced electrocata ly tic activ ity for the ox ygen reduction reac tion.
