All available thermodynamic and phase diagram data have been critically assessed for all phases in the MnO-TiO2, MgO-TiO2, FeO-TiO2, Ti2O3-TiO2, Na2O-TiO2, and K2O-TiO2 systems at 1 bar pressure from 298 K to above the liquidus temperatures. All reliable thermodynamic and phase diagram data have been simultaneously optimized to obtain, for each system,

Russian Journal of Physical Chemistry A, 2014
Three TiO2 loaded composites, TiO2/kaolin, TiO2/diatomite, and TiO2/zeolite, were prepared in order to improve the solar-light photocatalytic activity of TiO2. The results showed that the photocatalytic activity could obviously be enhanced by loading appropriate amount of inorganic mineral materials.

TiO2, TiO2/Ag and TiO2/Au photocatalysts prepared by spray pyrolysis
Journal of the European Ceramic Society, 2011Abstract TiO 2 , TiO 2 /Ag and TiO 2 /Au photocatalysts exhibiting a hollow spherical morphology were prepared by spray pyrolysis of aqueous solutions of titanium citrate complex and titanium oxalate precursors in one-step. Effects of precursor concentration and spray pyrolysis temperature were investigated.

Abstract The TiO 2 /Skeleton, TiO 2 /Dens and TiO 2 /HAP composites were prepared by sol–gel method. X-ray diffraction (XRD) and scanning electron microscope (SEM) were carried out to characterize them. Their photocatalytic activities were evaluated by degradation of Acid Red B under solar light irradiation. The results showed that the photocatalytic

Photocatalytic activity of Cu2O/TiO2, Bi2O3/TiO2 and ZnMn2O4/TiO2 heterojunctions
Catalysis Today, 2005Abstract Cu 2 O/TiO 2 , Bi 2 O 3 /TiO 2 and ZnMn 2 O 4 /TiO 2 heterojunctions were studied for potential applications in water decontamination technology and their capacity to induce an oxidation process under VIS light. UV–vis spectroscopy analysis showed that the junctions-based Cu 2 O, Bi 2 O 3 and ZnMn 2 O 4 are able to absorb a large part of

A study of the interactions of NO with Rh/TiO2 and TiO2-promoted Rh/TiO2
Journal of Catalysis, 1986Abstract The interactions of NO with Rh TiO 2 and TiO2-promoted Rh SiO 2 were studied by temperature-programmed desorption spectroscopy. The room-temperature chemisorption of NO was observed to decrease with increasing catalyst reduction temperature in a manner similar to that found for H2 and CO.

Surface Acidity and Photocatalytic Activity of TiO2, WO3/TiO2, and MoO3/TiO2 Photocatalysts
Chemistry of Materials, 1994TiO[sub 2] powder samples were calcined at various temperatures and their photocatalytic activity toward the degradation of 1,4-dichlorobenzene was measured. The surface acidity of the sample was also determined by the n-butylamine titration method. A linear relationship between photocatalytic activity and surface acidity was observed for the TiO[sub 2]

Study of TiO2 nanocrystallites in TiO2SiO2 composites
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998Abstract A titania-silica nanocomposite system with six different compositions (10/90, 20/80, 40/60, 50/50, 60/40, 80/20 molar ratio of TiO2/SiO2) was prepared by a sol-gel method. Different experimental techniques such as XRD, TEM, EDAX, DTA and density measurements by Archimedes' method were used to characterize each composition.
