摘要
以氯化亚锡和氧化石墨烯为前驱物制备了二氧化锡/石墨烯复合材料,并以其为载体担载了铂纳米颗粒催化剂,从而制备出铂/二氧化锡/石墨烯复合催化剂。所制备的铂纳米颗粒具有面心立方结构,二氧化锡是四方晶型;所制备催化剂的活性和抗中毒能力优于商业催化剂。
In this paper, stannous chloride and graphene oxide are employed as precursors to prepare SnO2/graphene composite. The as-prepared composite is used as support for Pt nanoparticles to prepare Pt/SnO2/graphene composite catalyst. The structure of as-prepared Pt nanoparticles is face-centred cubic and that of SnO2 is tetragonal. Both the CO poisoning resistance and electro-catalytic activity of the as-prepared catalyst are superior to commercial catalyst.
