摘　　要：仿照固氮酶合成氨的钼催化中心,二硫化钼基催化剂在电催化合成氨领域引起了人们的广泛关注。概述近几年用于电催化合成氨的具有不同相(2H、1T和3R)以及不同硫空位的二硫化钼。针对二硫化钼导电性不足、氮气吸附能力差的缺点,总结了几种常用的二硫化钼的改性方法,综述了改性后二硫化钼的电催化合成氨性能,指出了改性后二硫化钼电催化合成氨的反应机理。Following the molybdenum catalytic center of nitrogenase for ammonia synthesis,the molybdenum disulfidebased catalyst has attracted wide attention in the field of electrocatalytic ammonia synthesis.In this paper,of the molybdenum disulfide with different phases(2H,1T,and 3R)and different sulfur vacancies used for electrocatalytic ammonia synthesis in recent years was un introduced.In view of the shortcomings of insufficient conductivity and poor nitrogen adsorption capacity of molybdenum disulfide,several common modification methods of molybdenum disulfide were summarized,the electrocatalytic ammonia synthesis performance of modified molybdenum disulfide was discussed,and the reaction mechanism of electrocatalytic ammonia synthesis of modified molybdenum disulfide was pointed out.
