摘要
氢能作为一种零碳燃料,被认为是替代化石能源的理想能源.电催化析氢(HER)是一种绿色环保技术,可以裂解水分子制备氢气.因此开发低廉高效且稳定性好的非贵金属催化剂对于解决能源危机和可持续发展尤为重要.过渡金属磷化物(TMPs)具有良好的导电性、多变的化学组成、丰富的储量和稳定的理化性质,是HER反应重要的催化剂之一.本文首先介绍了HER反应机制及TMPs的结构特点,然后总结了TMPs的合成方法包括液相合成法和气-固合成法等,接着重点分析了现有TMPs的改性策略如形貌调控、缺陷调控、元素掺杂和界面复合,最后对未来TMPs的发展方向提出了展望.
Abstract
Hydrogen,a zero-carbon fuel,is supposed to be the potential alternative for fossil energy.Electrocataly-tic hydrogen evolution reaction(HER)is a green technology that could split water molecules to produce hydrogen.Therefore,exploring the low-cost,efficient and long-stable noble metal-free catalysts is particularly important for solving the problems of energy crisis and sustainable development.Transition metal phosphides(TMPs)possess excellent electrical conductivity,variable chemical composition,abundant reserves and stable physicochemical properties,which is one of the critical catalysts in HER.Herein,the HER mechanism and the structural characteris-tics of TMPs are introduced at first,then the fabrication approaches of TMPs like liquid phase formation,gas-solid synthesis,etc.are summarized.This paper are mainly focusing on the recent modification strategies for TMPs-based nanostructures,such as morphology regulation,vacancy creation,elemental doping and interface engineer-ing.Finally,the future directions for the development of TMPs is proposed.
