Titanium Dioxide Photocatalysts: Performance Related Properties

Abstract

The present work considers the performance-related properties of TiO2-based photosensitive semiconductors as photocatalysts for water purification and photoelectrodes for water splitting. These properties, including electronic structure, charge transport, surface properties, and near-tosurface properties, have an effect on light absorption and its conversion into chemical energy, and are closely related to defect disorder. Therefore, defect chemistry may be used as a framework for their modification in order to achieve enhanced performance. The present work considers the relationships between these specific performance-related properties and defect disorder.

Specifics of Structure Formation of Cement Stone with Silica Raw Material - A Substrate of Photocatalytic Composite Material

“…The advantage of this method is not only cleaning the surface, but also air cleaning [4,5]. In most cases, anatase titanium dioxide is used as a photocatalyst [6][7][8][9][10][11][12][13][14]. Due to its stability and activity, it does not participate in the reactions of structure formation of the cement composite.…”
