Suspension assisted synthesis of triblock copolymer-templated ordered mesoporous carbon spheres with controlled particle size

摘要

A general strategy in terms of large-scale and shape-controlled synthesis was used to design highly ordered mesoporous carbon spheres with controlled size from 50 to 500 urn by an evaporation induced organic-organic self-assembly inside ethanol-in-oil emulsions. Mesoporous carbon materials are widely used in adsorption, catalyst and electrode materials. Key to realization of these applications is to synthesize the materials into precise, predetermined nanostructures that can be preserved in a robust engineering form by a simple and efficient method. However, control over morphology and internal mesostructure of mesoporous carbons remains a challenge, especially when considering scaling laboratory synthesis up to industrial volumes.
