摘要
Abstract
High-ordered, Ti4+-incorporated, bimodal mesoporous material Ti-MCM-41 was synthesized from glass water and TiCl4 in a water-ethanol-surfactant system and characterized by small-angle X-ray diffraction, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, N2 adsorption-desorption, and high resolution transmission microscopy techniques. The results show that Ti4+ was in four coordinate in the framework of MCM-41. Furthermore, the zeolite primary units were formed in the framework. The Ti-MCM-41 sample had a bimodal mesoporous structure with the most probable pore sizes of 2.60 nm and 3.85 nm. The specific surface area of Ti-MCM-41 was 1 030 m2/g.关键词
