Construction Hierarchically Mesoporous/Microporous Materials Based on Block Copolymer and Covalent Organic Framework

Hierarchically ordered mesoporous materials have gained significant scientific attention due to their high surface areas, uniform porosity over various lengths scales, high-volume storage capability, shape selectivity, enhanced mass transport and diffusion. These materials have been widely applied in the fields of photocatalysis, separation, adsorption, photovoltaic solar cells, energy storage and conversion, chemical sensing, and drug delivery. In general, hierarchically porous materials can be generated in two ways: through sol-gel template approaches and a combination of surfactant-assisted procedures. In this review, we discuss recent progress in the preparation, properties, and potential applications of four hierarchically ordered porous materials: hierarchical mesoporous silica, mesoporous phenolic/carbon, nitrogen-doped mesoporous carbon, and mesoporous/microporous covalent organic frameworks.
