Electrocatalytic water splitting to produce clean hydrogen is a promising technique for renewable energy conversion and storage in the future energy portfolio. Aiming at industrial hydrogen production, cost-effective electrocatalysts are expected to be competent in both hydrogen evolution reactions (HERs) and oxygen evolution reactions (OERs) to accomplish the overall water splitting. Limited by the low tolerance and/or poor activity of most 1st-row transition metal-based electrocatalysts in strongly acidic media, bifunctional electrocatalysts are currently advocated to work at high pH values. Herein, this review summarizes the recent progress of nonprecious bifunctional electrocatalysts for overall water splitting in alkaline media, including transition metal-based phosphides, chalcogenides, oxides, nitrides, carbides, borides, alloys, and metal-free materials. Besides, some prevalent modification strategies to optimize the activities of catalysts are briefly listed. Finally, the perspective on current challenges and future prospects for overall water splitting driven by advanced nonprecious electrocatalysts are briefly discussed.

用于整体水分解的非贵金属和双功能电催化剂的最新进展

电催化水分解产生清洁的氢是未来能源组合中可再生能源转换和存储的有前途的技术。针对工业制氢，具有成本效益的电催化剂有望在氢析出反应（HER）和氧析出反应（OER）中发挥作用，以完成总的水分解。受大多数第一行过渡金属基电催化剂在强酸性介质中的低耐受性和/或较差的活性所限制，目前提倡双功能电催化剂在高pH值下工作。本文概述了非贵金属双功能电催化剂在碱性介质（包括基于过渡金属的磷化物，硫属化物，氧化物，氮化物，碳化物，硼化物，合金，和不含金属的材料。此外，简要列出了一些优化催化剂活性的普遍的改性策略。最后，简要讨论了由高级非贵金属电催化剂驱动的整体水分解的当前挑战和未来前景。
