A composition photocatalyst SiO 2 /TiO 2 based on nanodispersed titanium dioxide has been synthesized and its photocatalytic activity by oxidation of azo dye chrome brown has been studied. It is shown that the degree of decoloration of the chrome brown solution increases by 25%, when the content of the catalyst in the solution increases.
The influence of the oxygen pressure on the photochemical oxidation of phenol is investigated. It is shown that raising the oxygen pressure from 0.1 to 0.7 MPa leads to an increase in the photochemical oxi dation of phenol by a factor of approximately 3.7.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
