Abstract:

Functional mesoporous materials are a kind of porous solids with a pore size of 2-50 nm. They not only possess unique properties such as high specific surface area, pore size and uniform and controllable pore volume, but also have excellent optical, electrical and magnetic properties beyond inorganic functional nanoparticles. Normally, the functional mesoporous materials can be synthesized by soft-templating method, surfactant assembly process, however, their morphology and mesostructured are difficult to precisely control. In this lecture, I mainly introduce the recent progress in molecular aggregate super-assembly regulation, oriented assembly-controlled synthesis, and the construction of hierarchically-ordered functional mesoporous materials. We have demonstrated some new approaches for the synthesis of ordered functional mesoporous materials with hierarchical structures. We precisely prepared a family of novel functional mesoporous materials with hierarchical ordered structures, including uniform nanospheres, hemispheres, polyhedra, two-dimensional (2-D) single-layer nanosheets. These new mesoporous materials not only have unique and uniform morphology, but also have controllable mesopore structure, high specific surface area, large pore volume and open pore. We realized the orientation assembly of functional mesoporous materials, and created the asymmetric dumbbells, gourd, match, shuttlecock, double-leaf dimer (Y-type) multifunctional mesoporous materials for the first time. I will also introduce the applications of functional mesoporous materials in catalyst support, electrode materials for lithium-ion batteries, thermal insulation materials, dielectric materials (low-k) and other fields.
