Pt/CNFs-rGO催化剂的制备及催化氧化甲醇的性能研究
Platinum Nanoparticles Supported on the Compound of Carbon Nanofibers and Reduced Graphene Oxide for Methanol Electrooxidation
摘要
Abstract
Graphite oxide (GO) was synthesized by the improved Hummers' method.Carbon nanofibers (CNFs) were fabricated by combining the electrospinning and thermally treating.Then Pt nanoparticles were supported on the compound of CNFs and reduced graphene oxide (rGO) by a one-pot microwave heating method using ethylene glycol as the reducer.The performance of Pt/CNFs-rGO toward methanol electrooxidation was investigated by cyclic voltammetry and chronoamperometry methods in acidic electrolyte solutions.The results demonstrate that Pt/CNFs-rGO exhibits higher electrocatalytic performance toward methanol oxidation than Pt/CNFs,Pt/rGO and commercial Pt/C.The introduction of CNFs could enhance the electrocatalytic performance of Pt/rGO toward methanol oxidation.When the mass ratio of mrGO to mCNFs is 4 ∶ 3,the electrode of Pt/CNFs-rGO shows the best catalytic performance for methanol oxidation.The reason may be that the introduction of CNFs into the structure of rGO can avoid the stacking of graphene sheets effectively and improve the utilization of Pt nanoparticles.关键词
