Abstract:

Periodic ordered mesoporous silica materials with Ia3d cubic structure have been successfully synthesized by using ordered cubic mesoporous carbon CMK-8 as template via a nanocasting route, and subsequently characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen sorption measurement. The results reveal that the sample S4 possesses high hydrothermal stability.

Key words: Mesoporous silica; Hydrothermal stability; Nanocasting; Ia3d cubic structure
