摘要
石墨烯和其衍生物(氧化石墨烯、还原氧化石墨烯和掺杂石墨烯等)以独特的物理性质和可调变的表面化学性质在催化领域有巨大的应用潜力。首先简述石墨烯及其衍生物的制备方法和材料特性,接着归纳该材料在催化剂开发与应用中的研究情况,重点阐述石墨烯材料在催化剂中若干功能,包括作为载体负载金属/金属氧化物活性组分或嫁接有机官能团,作为结构助剂调变催化剂微结构,作为电子助剂调变活性组分电子特性,增强半导体材料的光催化功能,在催化剂的制备和分离过程中发挥可调变的两亲性作用,以及直接用作碳催化剂或无金属催化剂,并对石墨烯材料在催化领域的发展前景进行展望。
Graphene and its derivatives(mainly including graphene oxide,reduced graphene oxide and doped graphene)are of considerable interest in the field of catalysis science because of their unique physical properties and adjustable surface chemical properties.Here,we review recent advance in the preparation technology of graphene and its derivatives,and summarize the development of the graphene-based catalysts,with emphasis on the functions of graphene materials in catalysts,including as promising supp-orts to anchor metal/metal oxide nanoparticles or to graft organic functions,as additives to adjust the microstructure of catalysts,as promoters to tune the electronic states of active components,as assistants to promote the photocatalysis of semiconductors,adjustable amphipathy for catalyst preparation and separation,and as carbon catalysts or metal-free catalysts.The future opportunities and challenges of these graphene materials in catalysis utilization are also discussed.
