Composite photocalysts based on the nanostructural titanium dioxide and zirconium phosphate

Synthesis and studies of photocatalytic activity of composite based on nanodispersed TiO2 and SiO2

“…Nanodimensional titanium dioxide particles in combination with oxides, sulfides, and phosphates of other elements belong to a number of other composites which possess higher photocatalytic properties when compared with the initial TiO 2 [12,13]. Composites based on silica gels and titanium dioxide find application in photocatalytic processes as catalysts of oligomerization of olefines and polymerization of ethylene.…”

Heterogeneous composite titanium dioxide photocatalysts on phosphate supports

“…These supports must satisfy a series of requirements, namely, be chemically and thermally stable both during preparation of the photocatalyst and operation, have a highly developed surface, low concentration of surface recombination sites, and optical transparency in the spectral range actinic for TiO 2 . Taking account of additional requirements such as low cost, availability, lack of intrinsic toxicity and environmental danger, we have shown, in principle, the feasibility of using insoluble magnesium phosphate, aluminum phosphate, zirconium phosphate, titanium phosphate, and calcium phosphate as supports for TiO 2 photocatalysts [9][10][11]. In a continuation of these studies, we have compared the functional characteristics of titanium dioxide photocatalysts on phosphate supports relative to their chemical composition, structure, and method of preparation.…”
