摘要
氢能作为一种高能量密度、低分子质量以及无污染的绿色能源,未来有望替代传统能源。电解水制氢过程简单且是生产高纯度氢的重要方法,但水电解过程中反应动力学缓慢,严重影响电解水制氢的效率。过渡金属硫化物(TMSs)催化剂由于其低廉的价格和优异的电催化性能而成为研究重点。综述了TMSs催化剂最新研究成果和应用,以氢析出反应(HER)和氧析出反应(OER)的反应机理为出发点,通过电化学测试和电极表征的评估方法,重点介绍TMSs催化剂的制备方法及分析其在电催化水解制氢技术的研究进展。并针对TMSs催化材料面临的发展和问题进行讨论,为进一步提高TMSs的电解水制氢性能提供了崭新的思路。
As a green energy with high energy density,low molecular weight and no pollution,hydrogen energy is expected to replace traditional energy in the future.Electrolytic water hydrogen production process is simple and an important method to produce high-purity hydrogen,but the reaction kinetics in the process of water electrolysis is slow,which seriously affects the efficiency of electrolytic water hydrogen production.Transition metal sulfide(TMSs)catalysts have become the focus of research because of their low price and excellent electrocatalytic performance.This paper summarizes the latest research results and applications of TMSs catalysts.Starting from the reaction mechanism of hydrogen evolution reaction(HER)and oxygen evolution reaction(OER),Through the evaluation methods of electrochemical testing and electrode characterization,the development and problems faced by TMSs catalytic materials are discussed.It focuses on the preparation methods of TMSs catalysts and analyzes their research progress in electrocatalytic hydrolysis hydrogen production technology.It provides a new idea for further improving the hydrogen production performance of TMSs by electrolyzing water.
