摘要：Micron-sized hollow silica spheres whose shells are made up of mesocellular silica foams (MCFs) have been synthesized by one-pot sol-gel method in benzene/water/P123 emulsion. The material is characterized with SEM, TEM, BET and (29)Si MAS NMR. The results show that the MCFs of the unique shell of hollow silica spheres were connected by large windows with a narrow distribution of similar to 10 nm in diameter, the inner space of the hollow sphere is accessible. And the formation mechanism of the hollow silica spheres is proposed. (C) 2009 Xin Wen Guo. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
