摘要:
通过金属簇合物途径制备了碳载Pt-Au双金属纳米电催化剂.X-射线衍射和透射电镜结果表明合成的双金属纳米催化剂具有平均粒径小、粒径分布窄、相对结晶度低等特点.合成的Pt-Au/C催化剂经600℃热处理后粒径变化不大,表明合成的双金属催化剂具有较好的热稳定性.与商业化E-TEKPt/C催化剂相比,该催化剂对氧气还原反应呈现了较高的电催化活性.
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.
