石墨烯负载铂催化剂的制备及稳定性
Preparation and stability of patinum-loaded graphene catalyst
摘要
Abstract
Graphene oxide(GO) was prepared using grapheme powder as raw material. With GO and H2PtCl6 as precursor and ethylene glycol as solvent and reducing agent, composite catalyst Pt/Graphene was prepared by impregnation-reduction method. The as-prepared Pt/Graphene catalyst is characterized by X-ray powder diffraction, scanning electronmicroscopy and Raman spectroscopy. The results show that the Pt nanoparticles are dispersed into the graphene nanosheets by forming a face centered cubic crystal structure. The stability of the catalyst is evaluated by cyclic voltammetry and chronoamperometry. Compared with commercial catalyst, Pt/Graphene catalyst shows an improved electrochemical active area (ESCA) and electro catalytic activity. The Pt/Graphene catalyst has more favorable stability than the commercial catalyst.关键词
