摘　　要：石墨烯基气凝胶(GA)是一种内部连通的三维石墨烯宏观体,其在继承了石墨烯良好的化学稳定性和优良催化性能的同时拥有更高的比表面积和导电性。GA由于其优越的性能和独特的结构在催化、能量存储、吸附等领域得到广泛的应用。本文主要从GA催化还原特性展开,综述了具有不同催化性能的石墨烯基气凝胶的制备方法,将其总结归纳分为GA、掺杂型GA、复合型GA以及掺杂复合型GA四种类型,并详细介绍了制备方法对石墨烯基气凝胶催化性能的影响。石墨烯基气凝胶因具有优良的电化学活性和催化特性,在燃料电池、染料敏化太阳能电池、微生物电解池和电化学传感器等领域具有广泛的应用前景。最后对石墨烯基气凝胶在催化领域的应用前景进行分析和展望。Graphene-based aerogels（GA） are three-dimensional macrostructures of graphene with interconnected networks. While inheriting the excellent chemical stability and catalytic performance of graphene, GA exhibits higher specific surface area and excellent conductivity comparing to two-dimensional structure. Because of the superior properties and unique structure, GA are widely applied in catalysis, energy storage and adsorption. This review is expanded around the catalytic reduction performance of GA. Firstly, the preparation methods of GA with different catalytic properties are reviewed, which are classified into four types as graphene aerogels, doped GA, GA composite and doped GA composite. Then the influence on catalytic performance of GA prepared with different methods is introduced in detail. The admirable electrochemical and catalytic performance of GA indicates wide application prospects in fuel cells, dye-sensitized solar cells, microbial electrolysis cells and electrochemical sensors. Finally, the catalysis applications of GA are analysed and outlooked.
