通过热退火法制备了铝氮共掺杂石墨烯负载纳米钌复合催化剂(Ru/ANG),采用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射(XRD)、X射线光电子能谱(XPS)等手段对材料的结构与组成进行了表征。用作电催化剂时,Ru/ANG对氢燃料电池领域的3个重要反应——氧还原反应(ORR)、析氢反应(HER)和析氧反应(OER)均具有优异的电催化性能。该材料的发现对廉价多功能电催化剂的设计与开发具有重要的指导意义。
Al,N-codoped graphene(RGO) supported Ru nanocatalyst (Ru/ANG) was fabricated by the strategy of thermal annealing.The structure and component were characterized by scan electron microscopy (SEM),transmission electron microscopy (TEM),X-ray diffraction (XRD),and X-ray photoelectron spectroscopy (XPS).As electrocatalyst toward the three important reactions in hydrogen fuel cell,Ru/ANG exhibited outstanding electrocatalytic performance for oxygen reduction reaction (ORR),hydrogen evolution reaction (HER),and oxygen evolution reaction (OER).The catalyst developed here provided guidance for the design and exploration of highly efficient and cheap multi-functional electrocatalyst for energy storage and conversion.
