电解用于可持续制氢的水是各种新兴清洁能源技术的关键部分。然而，寻找一种高效、廉价的替代催化剂来取代最先进的铂族电催化剂仍然是该技术商业化的先决条件。通常情况下，无贵金属催化剂的制氢活性总是比铂族催化剂低得多。为了开发高性能的催化剂，最大限度地暴露活性中心、快速电荷转移能力和理想的电子构型是必不可少的。本文将简要介绍析氢反应的基本原理，重点介绍界面工程策略，包括构建缺陷结构、创建异质结、相工程、晶格应变控制、设计分层结构和掺杂杂原子，以有效地增殖催化活性中心，促进电子扩散，调节众多过渡金属及其氮化物、碳化物、硫化物、磷化物和氧化物的电子构型，从而实现无铂电极催化剂的基准性能。本综述明确地证明，通过合理、可控的界面设计，可以将传统的、廉价的、富含稀土的过渡金属基物质转化为活性裂水催化剂。
The electrolysis of water for sustainable hydrogen producing is a crucial segment of various emerging clean-energy technologies. However, pursuing an efficient and cheap alternative catalyst to substitute state-of-the-art platinum-group electrocatalysts remains a prerequisite for the commercialization of this technology. Typically, precious-metal-free catalysts have always much lower activities towards hydrogen production than that of Pt-group catalysts. To explore high-performance catalysts, maximally exposed active sites, rapid charge transfer ability and desirable electronic configuration are essentially demanded. Herein, the fundamentals of hydrogen evolution reaction will be briefly described and the main focus will be on the interfacial engineering strategies by means of constructing defect structure, creating heterojunction, phase engineering, lattice strain control, designing hierarchical architecture and doping heteroatoms to effectively proliferate the catalytic active sites, facilitate the electron diffusion and regulate the electronic configuration of numerous transition metals and their nitrides, carbides, sulfides, phosphides as well as oxides, achieving a benchmark performance of platinum-free electrocatalysts for the hydrogen evolution reaction. This review unambiguously offers proof that the conventional cheap and earth-abundant transition metal-based substances can be translated into an active water splitting catalyst by the rational and controllable interfacial designing.
