Photocatalytic Degradation of Methyl Orange by CeO2 and Fe–doped CeO2 Films under Visible Light Irradiation
Duangdao Channei,Burapat Inceesungvorn,Natda Wetchakun,S Ukritnukun,Andrew Nattestad,Jun Chen,Sukon Phanichphant +6 more
TL;DR: The 1.50 mol% Fe-doped CeO2 film was found to be the optimal iron doping concentration for MO degradation in this study and the presence of Fe3+ as found from XPS analysis, may act as electron acceptor and/or hole donor, facilitating longer lived charge carrier separation in Fe- doped Ce O2 films.

Effects of substituting Sr2+ and Ba2+ for Ca2+ on the structural properties and photocatalytic behaviors of CaIn2O4
TL;DR: In this paper, the substitution effects of M2+ ion on the structural and photocatalytic properties for methylene blue (MB) dye degradation were investigated systematically, and it was found that when M goes from Ca to Ba, the crystal structure of these materials changed from orthorhombic to monoclinic structure.

Enhancement of activity and sulfur resistance of CeO2 supported on TiO2-SiO2 for the selective catalytic reduction of NO by NH3.
TL;DR: A series of novel metal-oxide-supported CeO(2) catalysts were prepared via the wet impregnation method, and their NH(3)-SCR activities were investigated, revealing that the activity enhancement was correlated with the properties of the support material.

A neutral templating route to mesoporous molecular sieves.
TL;DR: A neutral templating route for preparing mesoporous molecular sieves is demonstrated based on hydrogen-bonding interactions and self-assembly between neutral primary amine micelles (S�) and neutral inorganic precursors (l�).

Titanium-containing mesoporous molecular sieves for catalytic oxidation of aromatic compounds
TL;DR: The use of the templating approach to synthesize mesoporous silica-based molecular sieves partly substituted with titanium—large-pore analogues of titanium silicalite find that these materials show selective catalytic activity towards the oxidation of 2,6-ditert-butyl phenol to the corresponding quinone and the conversion of benzene to phenol.

Titania-silica as catalysts : molecular structural characteristics and physico-chemical properties
Xingtao Gao,Israel E. Wachs +1 more
TL;DR: In this paper, the similarities and differences in structural characteristics and physico-chemical properties between titania-silica mixed and supported oxides are emphasized, and the generation of new catalytic active sites either on the silica surface or in the matrix is discussed with respect to the formation of Ti-O-Si bonds and the local structure.
