摘要 采用乙醇还原法制备了金属Pt/三苯胺烯共轭分子纳米复合物(Pt@DPSDA),通过UV-vis、TEM、FTIR、XRD、荧光、光电化学等方法对纳米复合物进行了表征。三苯胺烯分子通过分子末端羧基与金属Pt纳米粒子表面原子相互作用,形成以金属Pt纳米粒子为核,三苯胺烯分子为壳的核/壳型纳米复合物。光照下纳米复合物中激发态有机分子与金属Pt纳米粒子之间具有较好的电子转移作用,Pt@DPSDA纳米复合物可以作为催化剂在紫外-可见光照下分解水获得氢气。 Platinum/triphenylamine ethylene nanocomposite (Pt@ DPSDA) was prepared using an ethanol reduction method and characterized with UV-vis, TEM, FTIR, XRD, fluorescence spectroscopy, and photo-electrochemical method, respectively. Platinum core/conjugated organic molecule shell nanocomposite was formed as DPSDA molecules attached to the surface Pt atoms of platinum nanoparticles through carboxyl groups. DPSDA molecules in excited state may transfer photo-electron to the platinum nanoparticle. Under irradiation of UV-vis light, hydrogen was produced from photodecomposition of water using Pt@ DPSDA nanocompesite as the catalyst.
