Abstract:Nanoscale composite materials based on the SiO 2 -TiO 2 system were prepared in the form of co-precipitated composites and core SiO 2 -shell TiO 2 composites, with specific surface area 150-650 m 2 /g and sorption volumes 0.1-1.0 cm 3 /g. It is shown that variation of phase composition and morphology permits to change their structural-adsorption properties and nanocrystallites size after thermal treatment. It is discovered that co-precipitated composite materials differ from core SiO 2 -shell TiO 2 composites … Show more
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.
