Physical optics on the titanium dioxide pigments

On the Charge State of Titanium in Titanium Dioxide.

The oxidation state of titanium in titanium dioxide is commonly assumed to be +4. This assignment is based on the ionic approximation and is used ubiquitously to rationalize phenomena observed with TiO2. It implies a charge state +4 and that no further oxidation of the metal center is possible. We present a comprehensive electronic structure investigation of Ti ions, TiO2 molecules, and TiO2 bu...

The effect of titanium dioxide and molybdenum oxide on the properties of sodium potassium niobate piezoceramic

Sodium potassium niobate piezoceramics are considered as lead-free piezoelectric due to their good properties. In this study, the effect of titanium dioxide and molybdenum oxide as dopant on the densification behavior, piezoelectric and dielectric properties of lithium doped sodium potassium niobate ((K0.5Na0.5)0.94Li0.06NbO3, KNNL) was investigated. For this purpose, (K0.5Na0.5)0.94Li0.06Nb0.9...

Graphite / Titanium Dioxide Composite

Nanosized titanium dioxide (TiO2) in its anatase form is the most frequently studied and as well as used photocatalyst. There are several syntheses procedures which enable to achieve photocatalytic TiO2. The solgel method utilizing titanium alkoxides is used most often. Alternative precursors such as titanium tetrachloride and titanyl sulphate are also frequently employed. Nowadays the environm...

Investigation photocatalytic removal efficiency of phenol in Shadegan pond by thin layer of titanium dioxide nanoparticles sensitized with natural pigments

Phenolic compounds, such as phenol, are found to be significant in agricultural and industrial wastewater, especially in petroleum and petrochemical industries. Since these industries make up a large share of foreign exchange earnings, we have ignored from the huge contamination of them. we produces a large amount of wastewater from these industries and dispossessed them without proper purifica...
