可再生能源驱动的电化学水分解,已被认为是一种可持续和环保的生产绿氢的方式,是交通运输部门和难以减排的行业脱碳的重要载体,能够为实现全球碳中和做出贡献。为了大规模部署水电解槽,开发高效耐用的电催化剂至关重要。过渡金属碲化物(TMTs)具有成本低、稳定性好、过电位低、电子相互作用强、导电性好、活性位点多等优点,是在析氢反应(HER)和析氧反应(OER)中,传统铂族金属的有希望的替代品,已成为极具发展前景的电催化剂。本文综述了基于TMTs的HER和OER催化剂的最新研究进展,重点介绍了异质结构、掺杂、纳米结构工程等用于提高催化剂性能的各种策略,展望了未来基于TMTs催化剂的研究方向。

Electrochemical water decomposition driven by renewable energy was recognized as a sustainable and environmentally friendly way to produce green hydrogen,became an important vehicle for decarbonizing industries that were difficult to reduce emissions,and cold contribute to achieving global carbon neutrality.In order to deploy water electrolyzers on a large scale,it was essential to develop efficient and durable electrocatalysts based on cheap and earth-abundant materials.The transition metal tellurides(TMTs)became a promising substitute for traditional platinum group metals in hydrogen evolution reactions(HER)and oxygen evolution reactions(OER)due to their low cost,outstanding stability,low overpotential,strong electronic interactions,excellent conductivity,more active sites.This article provided a brief account of the latest development in TMT-based HER and OER catalysts,with a focus on various strategies developed to improve the catalytic performance,such as heterostructuring,dopant and nanostructure engineering.Perspectives of future research on TMT-based catalysts were also shortly outlined.
