摘要
近年来低成本的生物炭材料被用于电解水催化剂,对此展开综述。首先介绍电解水制氢基本原理及生物炭基催化剂的制备,再分析炭化温度、活化、杂原子掺杂、金属和/或金属化合物的负载对催化剂微观组成、性质及其催化活性的影响,以期为高效电解水制氢的生物炭基催化剂的制备提供参考。最后为提高电解过程中催化剂的长期稳定性、尤其OER和中性电解液下的催化活性,指出未来可在生物质原料的挑选、催化剂的电子结构调控及制备方法优化、理论计算指导4个方面做出努力。
In recent years,low-cost biochar have been used as electrocatalysts for electrolysis of water and that is reviewed in this paper.The basic principle of hydrogen production by electrolysis of water,preparation of biochar-based electrocatalysts are introduced firstly.Then the effects of carbonization temperature,activation,heteroatoms doping and metal and/or metal compound loading on the microscopic composition,properties and catalytic activity of the electrocatalysts are analyzed in order to provide a reference for the preparation of biochar-based electrocatalysts.Finally,it is pointed out that efforts can be made in the future in the selection of biomass raw materials,the regulation of the electronic structure of electrocatalysts and optimization of preparation methods,and theoretical calculation guidance,for improving the long-term stability and catalytic activity of biochar-based electrocatalysts,especially in OER and neutral electrolyte in the electrolysis process.
