钯/纳米石墨片复合材料的制备及其对甲醇的电催化性能
Facile preparation of Pd/graphite nanoplate composites for electrocatalytic oxidation of methanol
摘要
Abstract
Graphite nanoplates were prepared by combining the modified Hummers and mechanical stripping method. Pd nanoparticles supported on graphite nanoplates were successfully synthesized by a simple one-step reduction method with sodium borohydride as the reducing agent. The results show that this new method for the preparation of graphite nanoplates is simple, fast and efficient. Pd nanoparticles with an average size of 11.5 nm are well dispersed on the surface of graphite nanoplates. The composite materials exhibited excellent catalytic activity and poison resistance for the electro-oxidation of methanol in alkaline medium, superior to the Pd supported on the reduced graphene oxide prepared by traditional modified Hummers method and commercial carbon black Vulcan XC-72, respectively.关键词
