Abstract

Three types of mesoporous materials were observed directly by field emission-scanning electron microscopy (FE-SEM). The effects of accelerating voltage on these materials are discussed. Our results show that low-accelerating voltage could facilitate the observation of SBA-15 and TUD-1 mesoporous zeolite. However, as for mesoporous silica nano-spheres, high-accelerating voltage was helpful for the observation of surface structure.
