摘　　要：氢能是一种高效清洁的能源,采用太阳能等绿电电解水制氢已成为关注的热点,寻找高效廉价的析氢催化剂是电解水制氢的关键。以廉价的球形石墨尾料为原料,采用改良Hummers法制备的氧化石墨烯(Graphene oxide,GO)作为催化剂载体前驱体,并利用一步水热法将Ni_(0.85)Se负载于还原氧化石墨烯(reduced graphene oxide,rGO)上合成Ni_(0.85)Se/rGO作为电解水析氢催化剂材料。将rGO作为载体可以有效降低Ni_(0.85)Se的团聚,增加催化析氢的活性,Ni_(0.85)Se/rGO电极在10 mA·cm-2电流密度时的析氢过电位为167 mV,且具有良好的稳定性。Hydrogen energy is an efficient and clean energy source,and hydrogen production from water electrolysis using green electricity such as solar energy has become a hot topic.However,finding efficient and inexpensive hydrogen evolution catalysts is the key to electrolysis of water for hydrogen production.Graphene oxide(GO)was used as catalyst carrier precursor which was prepared by modified Hummers method with inexpensive spherical graphite tail as raw material,and Ni_(0.85)Se/rGO was prepared by one-step hydrothermal method as catalyst material for hydrogen evolution.The aggregation of Ni_(0.85)Se can be effectively reduced and the catalytic activity for hydrogen evolution can be increased through using rGO as the catalyst carrier.At the current density of 10 mA·cm-2,the hydrogen evolution overpotential of Ni_(0.85)Se/rGO is 167 mV,and it has good stability.
