Photoreduction of Nitrogen on TiO2 and TiO2-Containing Minerals

2011
A report appearing in 1975 demonstrated that incompletely out-gassed, powdered titanium dioxide photo-reduces acetylene to ethylene and prompted attempts to achieve the photoreduction of molecular nitrogen under similar conditions. Whereas pure, powdered anatase was only slightly active, a substantial enhancement of its photocatalytic activity was ...

A 1H NMR study of reduced Ru/TiO2 and TiO2

Colloids and Surfaces, 1989
Abstract Oxides and metals dispersed on oxide supports form an important commercial class of high surface area heterogenous catalysts. The understanding of the nature of the surface and its function is a fundamental requirement in the design of more efficient, selective catalysts.

The investigation of X-ray OK??- and TiL??-emission bands in coarse-(???d > 5 ??m) and nanopowders (???d = 107 and 10 nm) reveals the narrowing and a change of their shape, that is due to the energy redistribution of valence electrons in the Op-states after the break of atomic bonds during the dispersion of the material to nanosizes.

[Groundwater Arsenic and Silicate Adsorption on TiO2 and the Regeneration of TiO2].

Huan jing ke xue= Huanjing kexue, 2019
Titanium dioxide (TiO2) was widely used to remove arsenic (As) from groundwater due to its excellent properties. Previous studies show that the coexisting silicate ions (Si) could occupy the available surface sites of TiO2 and further inhibit As adsorption and TiO2 regeneration.

Dye sensitized solar cell with Fe2O3/TiO2, WO3/TiO2 OR CeO2/TiO2 electrode layer

A titanium dioxide electrode layer for a dye-sensitized solar cell (DSSC) was prepared from ultrasonic spray coating of TiO₂ sol, which was synthesized via a sol-gel method. The effects of sintering temperature, film thickness, and modification of TiO₂ layer by another metal oxide on the efficiency of the dye-sensitized solar cell were studied.
