摘　　要：石墨烯是以sp2杂化轨道组成的六角型蜂巢状二维碳纳米材料,具有比表面积大、导电性好和机械强度高等优点,在电催化领域被广泛应用,但也存在易堆叠、活性位点少等不足。石墨烯材料电催化活性与其原子排列、分子吸附和活化、电子结构、电荷运输等相关,综述了通过掺杂调控提高其内在活性、界面调控实现不同组分之间的协同作用、相调控改变原子排布方式、结构调控改变局部环境促进电子和质量传递等改善石墨烯材料电催化性能的方法,指出将掺杂调控与其他3种活性调控方法有机结合是未来的发展方向。Graphene is a hexagonal honeycomb-shaped two-dimensional carbon nanomaterial composed of sp 2 hybrid orbitals,with the advantages of large specific surface area,good electrical conductivity and high mechanical strength.Although widely used in the field of electrocatalysis,it also has the disadvantages of easy stacking and few active sites.The electrocatalytic activity of graphene materials is related to its atomic arrangement,molecular adsorption and activation,electronic structure,and charge transport.This paper reviews the methods of improving the electrocatalytic performance of graphene materials,such as improving their intrinsic activity through doping regulation,realizing the synergy between different components through interface control,changing atomic arrangement through phase control,and changing local environment through structural control.And it is pointed out that the organic integration between the doping regulation with the other three active regulation methods is the future development direction.
