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 gas-phase 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.
