Research progress of photocatalysis based on highly dispersed titanium in mesoporous SiO2

摘要

With the development of the human economy and green chemistry, people pay much more attention to environmental safety. Correspondingly, mesoporous TiO2 and its correlated photocatalysts are able to help people seek for better life. In this review, first of all, we briefly introduce the preparations and applications of mesoporous TiO2-SiO2 materials, which exhibit excellent performance in pollutants decomposition and H2 evolution in photocatalysis. Then, we review the mesoporous composites of Ti-SiO2 materials, which are ideal materials used in the photoreduction of air pollutants such as CO2, NO and NO2. It is powerfully evident from the literature surveys that these TiO2 based mesoporous photocatalysts possess a large potential in environment and energy development.
