摘要

Monolithie and transparent Ti-incorporated mesoporoussilica materials of largesize(e.g.2mm) in dimension have been prepared with tartaric acid(TA)as template via sol-gel reac-tions of tetraethyl orthosilicate (TEOS)and tetrabutyl titanat (TBT).The materials are characterized by infrared (IR),nitrogen adsorption-desorption istherms,powder X-ray diffraction(XRD)and transmission electron microscopy (TEM).The results indicate that the monolithic materials ex-hibit large specific surface(ca.1200m 2/g)and pore volumes (ca.0.900cm3/g).
