摘　　要：有序介孔碳基金属复合材料具有较大的比表面积、规整的孔道结构、良好的热稳定性及化学稳定性、活性金属组分分散度高以及粒径尺寸小等特点,广泛应用于非均相催化领域。常用的合成方法包括浸渍法、"一锅"法以及金属组分转移法等。本文综述了近年来有序介孔碳基金属复合材料的制备及其在非均相催化领域中的应用研究进展,重点阐述了介孔碳载体的介观结构调控、表面性质控制及限域效应等对所负载的活性金属组分的分散性、粒径大小,以及对反应物和产物扩散的影响,探讨了其在气相反应、液相反应和光电催化等领域的应用,并对有序介孔碳基复合材料的发展方向和应用前景进行了展望。Ordered mesoporous carbon-based metal composite materials have attracted much research interests due to their large surface area,uniform pore size,high thermal stability and chemical inertness,and the loaded active metal components with small particle size and high dispersion, which have been widely used in heterogeneous catalysis. The common preparation methods include impregnation method,＂one-pot ＂method,and metal component transfer method. This paper reviews the research progress of the application of ordered mesoporous carbon as catalyst and support in the field of heterogeneous catalysis,focusing on the structure control,surface properties control,confinement effect of the carbon support that influence on dispersion,particle size,the diffusion of reactant and product. The particle size and dispersion degree of the active metal combine with unique ordered mesoporous carbon support,which contribute to improve the catalytic performance in gasphase catalytic reactions,liquid-phase catalytic reactions,and photoelectric catalysis,can be controlled by modification of the mesoporous carbon carrier and various preparation strategies. Furthermore,remarks on the challenges and perspectives of research directions are proposed for further development of the order mesoporous carbon based metal composite materials.
