Bimodal mesoporous materials are new hierarchical materials with small mesopores and large mesopores simultaneously.These materials have great potential applications in adsorption and catalytic fields,and have already aroused much attention.This paper summarizes the synthesis approaches of bimodal mesoporous materials and their application in adsorption and catalysis.In addition,the development trend is dicussed including the effective control of bimodal mesoporous structure and pore spatial distribution,the characterization of pore structure and physicochemical properties,and the application investigation.
