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 nanocomposite as the catalyst.
