This review summarizes the recent theoretical progress on the well-defined surfaces of TiO2 crystalline. It focuses on the structures, adsorptions, and reactions on the surface and at the interface. Theoretical methods and models, as well as applications of TiO2 in various fields, are discussed in detail.
Titanium dioxide (TiO2) is one of the most technologically promising oxides with a broad range of catalytic and photocatalytic activities. Theoretical modeling, especially density functional theory calculations, has been extensively carried out to understand the geometric structure, electronic structure, reactivity, and reaction mechanisms of TiO2 systems, as well as to develop new catalysts with improved performances. This review summarizes the recent theoretical progress on the well-defined surfaces of TiO2 crystalline, and focuses on the structures, adsorptions, and reactions on the surface and at the interface. The theoretical methods and models, surface defects, surface doping, water splitting and H-2 evolution, methanol conversion, CO2 reduction and CO oxidation, SOx and NOx degradation, CH4 conversion, organic pollutant degradation, C-H bond activation and C-C bond formation, dye sensitization, as well as the applications of TiO2 in some other fields, have been discussed in detail.
