氮、硫共掺杂多孔类石墨烯碳催化剂的制备及其氧还原性能
Preparation and catalytic performance toward oxygen reduction reaction of a N, S codoped porous graphene-like carbon-based electrocatalyst
摘要
Abstract
Low-cost and high performance electrocatalysts toward oxygen reduction reaction (ORR) is important for novel energy systems,such as proton exchange membrane fuel cells,direct methanol fuel cells,and etc.In this work,a N and S codoped porous grapheme-like catalyst was obtained using polyacrylonitrile and sulfur as precursors through a facile pyrolysis procedure.The catalyst exhibited excellent performance in alkaline medium,with a half-wave potential 32 mV more positive than that of commercial Pt/C catalyst.Beside excellent ORR performance,the catalyst also exhibited outstanding methanol tolerance,stability,as well as high catalytic efficiency.By studying the relationship among catalyst`s structures,compositions and its catalytic performance,we found that the unique compositions,morphologies and porous structures induced by sulfur addition should be the origin to the catalyst`s high ORR performance.关键词
