Highly porous Au-Pt urchin-like bimetallic nanocrystals have been prepared by a one-pot wet-chemical synthesis method. The porosity of urchin-like bimetallic nanocrystals was controlled by amounts of hydrazine used as reductant. The prepared highly porous Au-Pt urchin-like nanocrystals were superior catalysts of electrochemical methanol oxidation due to high porosity and surface active sites by their unique morphology. This approach will pave the way for the design of bimetallic porous materials with unprecedented functions.
通过一锅湿化学合成法制备了具有高度多孔性的金-铂海胆状双金属纳米晶体。海胆状双金属纳米晶体的孔隙率由用作还原剂的肼的用量控制。所制备的具有高度多孔性的金-铂海胆状纳米晶体由于其独特的形态具有高孔隙率和表面活性位点，是电化学甲醇氧化的优异催化剂。这种方法将为设计具有前所未有的功能的双金属多孔材料铺平道路。
