Research progress of photocatalysis based on highly dispersed titanium in mesoporous SiO <inf>2</inf>

Abstract

With the development of the human economy and green chemistry, people pay much more attention to environmental safety. Correspondingly, mesoporous TiO 2 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 TiO 2 -SiO 2 materials, which exhibit excellent performance in pollutants decomposition and H 2 evolution in photocatalysis. Then, we review the mesoporous composites of Ti-SiO 2 materials, which are ideal materials used in the photoreduction of air pollutants such as CO 2 , NO and NO 2 . It is powerfully evident from the literature surveys that these TiO 2 based mesoporous photocatalysts possess a large potential in environment and energy development.
