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

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 TiSiO₂ 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.
