摘要:
通过溶液中等离子法快速制备Pt纳米颗粒,选用TiO2(P25)提升Pt纳米颗粒的电催化性能,并以石墨烯纳米片(GNs)为载体材料,通过简单的超声混合制备Pt/GNs/TiO2催化剂。采用X线衍射仪(XRD)、透射电子显微镜(TEM)、X线光电子能谱仪(XPS)及循环伏安曲线(CV)测试等表征手段分析样品的组成、形貌、表面电子特性及对甲醇的电催化性能。结果表明:制备得到了在GNs表面分布均匀、结晶性良好并且直径为2~5 nm的Pt纳米颗粒,同时TiO2也成功分散在GNs表面。加入TiO2极大地提高了Pt纳米颗粒对甲醇的电催化活性,Pt/GNs/TiO2的电流密度约为2 480 mA/mg,是未加入TiO2的Pt/GNs(747 mA/mg)的3.3倍,同时其循环性能和抗中毒性能也得到了提升。
Abstract:
Pt nanoparticles were synthesized by solution plasma technique.The TiO2 nanoparticles(P25)were used to enhance the electro-catalysis properties of Pt nanoparticles with graphene nanosheets(GNs)as the support material.The Pt/GNs/TiO2 catalyst was obtained by ultrasonic mixing.The structure,morphology,component,methanol oxidation performance and cycling stability of the as-obtained catalyst were characterized by X-ray diffraction(XRD),transmission electron microscope(TEM),energy dispersive X-ray(EDX)and cyclic voltammogram measurement,respectively.Results showed that well crystallized Pt nanoparticles in the size range of 2-5 nm were produced, and Pt and TiO2 nanoparticles were well dispersed on the surface of graphene nanosheets.The Pt/GNs/TiO2 exhibited excellent electro-catalytic activity with 3.3 times higher compared with that of Pt/GNs,stability and poisoning resistance towards methanol electro-oxidation.
