摘要:

解决全球气候变化和能源危机的有效途径之一是用氢能源(H2)代替传统的化石能源. 析氢反应(Electrochemical hydrogen evolution reaction, HER) 被认为是绿色环保的可持续产氢途径, 通常电解过程需要催化剂以降低电化学电位, 提高能量利用效率. 目前最先进的催化剂仍然依赖于贵金属, 但是研究表明, 过渡金属二硫族化物(Transition metal dichalcogenides, TMDs)同样具有优异的催化活性, 与贵金属相比, TMDs产量大、 价格低、 催化活性好、 便于调控和修饰, 有望替代贵金属在催化领域的应用. 基于此, 本文讨论了近年来TMDs在析氢方面的研究情况以及TMDs材料的性能调控, 包含原子工程、 相工程和异质结. 并总结和展望了TMDs催化材料的挑战与机遇.

Abstract:

To solve the global climate change and energy crisis, one of the most effective alternative energy sources is hydrogen(H2). Hydrogen evolution reaction(HER) is regarded as green process for the sustainable production of hydrogen, usually requiring a catalyst to reduce the electrochemical potential and improve the conversion efficiency. Currently the most advanced catalyst still relies on precious metals. Recent research shows that the transition metal dichalcogenides(TMDs) also has excellent catalytic activity. Comparing to precious metals, TMDs are expected to be the alternatives to precious metals in the field of catalysis. Based on this, this review discusses the researches of TMDs in hydrogen evolution reaction in recent years and strategies to improve catalysis activity, including atomic engineering, phase engineering and heterogeneous junction. Finally, the challenges and opportunities of TMDs catalytic materials are concluded.

Key words: Transition metal dichalcogenides, Hydrogen evolution reaction, Atomic engineering, Phase engineering, Heterostructure
