为了解决二氧化碳排放的全球问题，氢是向环境燃料电池电动机过渡的所需能量载体。电力来源，WE的宽度实施的主要障碍之一是用于催化阴极氢的铂金属金属（PGM）的稀缺和高成本进化反应（HER）和阳极氧的演化反应（OER）。对WE应用中使用的无PGM材料，重点是磷化物和基础知识。总体而言，讨论了催化剂对OER活性的晶体和电子结构，形态和表面化学的影响。
To combat the global problem of carbon dioxide emissions, hydrogen is the desired energy vector for the transition to environmentally benign fuel cell power. Water electrolysis (WE) is the major technology for sustainable hydrogen production. Despite the use of renewable solar and wind power as sources of electricity, one of the main barriers for the widespread implementation of WE is the scarcity and high cost of platinum group metals (pgms) that are used to catalyse the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER). Hence, the critical pgm-based catalysts must be replaced with more sustainable alternatives for WE technologies to become commercially viable. This critical review describes the state-of-the-art pgm-free materials used in the WE application, with a major focus on phosphides and borides. Several emerging classes of HER and OER catalysts are reviewed and detailed structure‐property correlations are comprehensively summarised. The influence of the crystallographic and electronic structures, morphology and bulk and surface chemistry of the catalysts on the activity towards OER and HER is discussed.
