Structural design in the silicate framework of ordered mesoporous silica derived from kanemite

摘要：

The silicate framework of ordered mesoporous silica KSW-2 was chemically designed and structurally stabilized by direct silylation of the mesostructured precursor using silylating agents such as octoxytrichlorosilane (C8H17OSiCl3) and octylmethyldichlorosilane (C8H17- (CH3)SiCl2). Depending on the molecular structures of the silylating agents, pure silica type and surface-modified type mesoporous materials can be obtained with the retention of the molecularly ordered framework because of the presence of the new silicate units strengthened by silylation, and the framework was thermally more stable.
