Hydrogen production from electrochemical water splitting represents a highly promising technology for sustainable energy storage, but its widespread implementation heavily relies on the development of high-performance and cost-effective hydrogen evolution reaction (HER) electrocatalysts. Metal oxides, an important family of functional materials with diverse compositions and structures, were traditionally believed inactive towards HER. Encouragingly, the continuous breakthroughs and significant progress in recent years (mainly from 2015 onwards) make engineered metal oxides emerge as promising candidates for HER electrocatalysis. In this article, we present a comprehensive review of recent advances in metal oxide-based electrocatalysts for HER. We start with a brief description of some key fundamental concepts of HER, such as mechanisms, computational activity descriptors, and experimental parameters used to evaluate catalytic performance. This is followed by a overview of various types of metal oxide-based HER electrocatalysts reported so far, including single transition metal oxides, spinel oxides, perovskite oxides, metal (oxy)hydroxides, specially-structured metal oxides and oxide-containing hybrids, with special emphasis on designed strategies for promoting performance and property–activity correlation. Finally, some concluding remarks and perspectives about future opportunities of this exciting field are provided.

金属氧化物基材料作为一种新兴的析氢电催化剂家族

电化学水分解产生的氢气代表了可持续储能的极有前途的技术，但其广泛实施在很大程度上取决于高性能和经济高效的析氢反应（HER）电催化剂的开发。传统上认为金属氧化物是具有不同组成和结构的功能材料的重要家族，对HER没有活性。令人鼓舞的是，近年来（主要从2015年开始）的不断突破和重大进展使工程金属氧化物成为HER电催化的有希望的候选者。在本文中，我们对HER的基于金属氧化物的电催化剂的最新进展进行了全面综述。我们首先简要介绍HER的一些关键基本概念，例如机制，计算活性描述符和用于评估催化性能的实验参数。接下来是迄今为止报道的各种类型的基于金属氧化物的HER电催化剂的概述，包括单过渡金属氧化物，尖晶石氧化物，钙钛矿氧化物，金属（氧）氢氧化物，特殊结构的金属氧化物和含氧化物的杂化物，以及特别强调设计的策略，以促进性能和财产-活动相关性。最后，提供了有关这一激动人心领域的未来机会的一些总结性意见和观点。钙钛矿氧化物，金属（氧）氢氧化物，特殊结构的金属氧化物和含氧化物的杂化物，特别着重于提高性能和性能-活性相关性的设计策略。最后，提供了有关这一激动人心领域的未来机会的一些总结性意见和观点。钙钛矿氧化物，金属（氧）氢氧化物，特殊结构的金属氧化物和含氧化物的杂化物，特别着重于提高性能和性能-活性相关性的设计策略。最后，提供了有关这一激动人心领域的未来机会的一些总结性意见和观点。
