PVP络合剂对Pt/Gr催化甲醇氧化性能的影响
Effects of PVP on catalytic performance of Pt/Gr catalysts for methanol oxidation
摘要
Abstract
Pt/Gr catalysts were prepared by organic-sol method with polyvinylpyrrolidone (PVP) as complexing agent.The catalysts were characterized by FT-IR, XRD and TEM, and the electrocatalytic performances of the catalysts for methanol oxidation in acid solution were measured.The results showed that the addition of appropriate amount of PVP could greatly improve the dispersion of Pt nanoparticles of Pt/Gr catalysts and reduce the particle size.The electrocatalytic performance and stability of Pt/Gr for methanol oxidation increased with the PVP contents firstly, and then decreased.When the maximum electrocatalytic activity (current density 0.53 A/mgPt) was reached,it was 2.4 times higher than that of Pt/Gr prepared without PVP,and Pt/Gr had higher stability at PVP content=10 mg.关键词
