摘要
随着全球能源需求增长及环境污染问题加剧,开发高效环保的能源转换与存储技术至关重要.煤焦油沥青(CTP)作为煤焦油蒸馏后的残留物,具有高含碳量、成本低、芳香度高、易石墨化等优势,是制备多孔碳材料的优质碳源.本文综述了CTP的组成与性质,重点探讨了预氧化、预碳化、杂原子掺杂、活化、模版法及熔融盐阻燃6种修饰方法,这些手段可有效改善CTP结构,提高材料性能.在氧还原反应(ORR)应用方面,CTP基材料展现出良好的应用前景,本文对此进行了概述.
With the growth of global energy demand and the aggravation of environmental pollution problems,the development of efficient and eco-friendly energy conversion and storage technologies is crucial.Coal tar pitch(CTP),as a residue after coal tar distillation,has the advantages of high carbon content,low cost,high aromaticity,and easy graphitisation,and is a high-quality carbon source for the preparation of porous carbon materials.This paper reviews the composition and properties of CTP,focusing on six modification methods,namely,pre-oxidation,pre-carbonization,heteroatom doping,activation,templating and molten salt stabilization,which can effectively improve the structure of CTP and enhance the material properties.In terms of oxygen reduction reaction(ORR)applications,CTP-based materials show good application prospects,which are outlined in this paper.
