An overview on the physicochemical properties and photocatalytic pollutant removal performances of TiO2-incorporated cementitious composites

Abstract

Recently, the use of TiO2 as a phtocatalyst has been diversely investigated due to its excellent durability performance and high photocatalytic reaction efficiency. Active researches have particularly focused on the development of TiO2-incorporated cementitious composites in order to remove the atmospheric pollutants. Furthermore, the potential utilization of TiO2-incorporated cementitious composites as road accessories such as tunnels, road median separators and soundproof walls in the form of tiles, blocks and structural components has been widely examined. In this regard, a thorough understanding on the material characteristics of TiO2-incorporated cementitious composites should be preceded. The present overview article, therefore, revisits previous studies of TiO2-incorporated cementitious composites and summarizes their various physicochemical properties and atmospheric pollutants removal performance.
