摘　　要：过渡金属基材料成本相对较低,催化性能较为优异,是在全水分解领域最有希望替代贵金属基电催化剂的候选材料之一,但有限的活性位点、相对较差的电导率等因素限制了其广泛应用。非金属元素掺杂能够调节主体材料电子结构,优化吸附能,从而对过渡金属基电催化剂的活性与稳定性产生积极影响,缩减其与贵金属材料性能差距。本文总结了近年来非金属元素改性在过渡金属基电催化材料中的相关研究,系统综述了非金属元素掺杂的方法和不同非金属元素的掺杂效果,从物理化学性质的改变和电子结构的变化多角度分析了非金属元素改性对过渡金属基材料的影响,最后对非金属元素掺杂过渡金属基电催化剂的未来发展方向作出了展望。Transition metal-based materials with relatively low cost and excellent catalytic performance are considered as the most promising candidates to replace noble metal-based electrocatalysts in the field of overall water splitting.However,their wide applications are hindered by the limited active sites and relatively poor electrical conductivity.The doping of non-metallic elements can modulate the electronic structure of the host material and optimize the adsorption energy,thus positively affecting the activity and stability of transition metal-based electrocatalysts and narrowing the performance gap between them and precious metal materials.In this paper,we summarize the recent research on the modification of non-metallic elements in transition metal-based electrocatalytic materials,systematically review the methods of non-metallic element doping(high-temperature calcination,hydrothermal/solvent thermal,plasma treatment and electrodeposition),the doping effects of different non-metallic elements(single non-metallic element doping,multi-nonmetallic element doping and composite doping),and analyze the effects of non-metallic element modification on transition metal-based electrocatalysts from multiple perspectives of physicochemical property changes and electronic structure changes.The effects of non-metallic element modification on transition metal-based materials are analyzed from the perspectives of physicochemical property change and electronic structure change.In the end,the future development direction of non-metallic element doped transition metalbased electrocatalysts is prospected.
