摘要
氢能在可持续能源和绿色发展中发挥着重要的作用。水电解被认为是实现规模化制氢的有效方法之一。开发低成本的高效析氢反应(HER)电催化剂是破解传统贵金属资源短缺的瓶颈限制的关键。过渡金属硫/氧化物因其来源丰富、成本低廉,尤其是具有丰富可调控的电子结构已被证明是能替代贵金属的优良析氢反应催化剂。本文综述了近年来国内外过渡金属硫/氧化物在碱性电解水析氢反应中的研究成果,梳理了各种提高过渡金属硫/氧化物催化性能的策略,最后展望了过渡金属硫/氧化物电催化材料未来的发展趋势,提出了氢能可持续发展的方向。
Hydrogen energy plays an important role in the sustainable energy and green development.Water electrolysis for hydrogen generation is considered as one of the most effective green methods to achieve the large-scale hydrogen production.The key to solve the bottleneck of resource shortage for the traditional precious-metal electrocatalysts is to exploit low-cost and highly-efficient electrocatalysts towards hydrogen evolution reaction(HER).Transition metal sulfides/oxides have been proven as excellent HER electrocatalysts to replace precious-metal electrocatalysts because of their abundant resources and low costs,especially their plentiful and tunable electronic configurations.In this review,the recent research achievements in the application of transition metal sulfides/oxides in the alkaline water electrolysis towards HER and various strategies to improve their catalytic performances are summarized and discussed.Finally,the future development trend of transition metal sulfide/oxide electrocatalysts towards HER is prospected and the sustainable development direction of hydrogen energy is proposed.
