Electrochemical water splitting is a promising technology for sustainable conversion, storage, and transport of hydrogen energy. Searching for earth-abundant hydrogen/oxygen evolution reaction (HER/OER) electrocatalysts with high activity and durability to replace noble-metal-based catalysts plays paramount importance in the scalable application of water electrolysis. A freestanding electrode architecture is highly attractive as compared to the conventional coated powdery form because of enhanced kinetics and stability. Herein, recent progress in developing transition-metal-based HER/OER electrocatalytic materials is reviewed with selected examples of chalcogenides, phosphides, carbides, nitrides, alloys, phosphates, oxides, hydroxides, and oxyhydroxides. Focusing on self-supported electrodes, the latest advances in their structural design, controllable synthesis, mechanistic understanding, and strategies for performance enhancement are presented. Remaining challenges and future perspectives for the further development of self-supported electrocatalysts are also discussed.

自支撑过渡金属基氢和氧逸出的电催化剂。

电化学水分解是一种可持续发展的氢能转化,存储和运输的有前途的技术。在水电解的可扩展应用中,寻找具有高活性和耐久性的富含地球的氢/氧放出反应(HER / OER)电催化剂来替代贵金属基催化剂至关重要。与传统的涂层粉末形式相比,自立式电极结构具有很高的吸引力,因为它具有增强的动力学和稳定性。本文中,以硫属化物,磷化物,碳化物,氮化物,合金,磷酸盐,氧化物,氢氧化物和羟基氧化物的选定实例综述了开发基于过渡金属的HER / OER电催化材料的最新进展。专注于自支撑电极,其结构设计的最新进展,提出了可控的合成,机理理解和性能增强策略。还讨论了自担负电催化剂进一步发展的剩余挑战和未来前景。
