"Oriented Assembly of Functional Mesoporous Materials on Interface"

Abstract:

Mesoporous materials possess several fascinating properties, including uniform pore size ranging from 2.0 to 50 nm, high surface areas, large pore volumes, tunable mesostructures, morphologies and framework compositions, showing advantageous for applications in various areas such as energy conversion and storage, environment remediation, and biomedical science. Particularly, creating high-performance mesoporous materials with precisely controllable “multifunctional entities” are highly desired for the development of material science and practical applications. Here we present the development and progress for the synthesis of the spherical functional mesoporous nanoparticles from novel “oriented assembly” strategy by interfacial control. A series of new synthesis approaches have been developed based on the oriented assembly strategy in my group, including the confined micro-emulsion self-assembly, liquid-liquid bi-phase synthesis, evaporation-driven oriented/aggregation assembly, anisotropic growth of mesoporous, and interface driven orientation arrangement, etc. Novel mesoporous nanospheres with one-level and multi-level architectures can be well synthesized, such as core-shell, yolk-shell, multi-shell, film structures for silica, TiO2, carbon spheres, 3D mesoporous bouquet-posy-like TiO2 multi-level superstructures and asymmetric Janus, single-hole hollow, nano-thermometer, hemispheres structures etc. The obtained functional mesoporous nanospheres with regularly multi-level architectures possess uniform and controllable mesopore channels, high surface area, large pore volume and open frameworks, showing great potential applications on catalysis, adsorption & separation, biomedicines and energy conversion & storage.
