Abstract

Abstract : This review covers the various synthetic methods of doped and undoped TiO2 nanomaterials, ranging from single‐doped and co‐doped to multidoped with transition‐metal ions, rare earth metal ions, and other metals and nonmetals ions. The effects of doping on the physiochemical propertiesas well as the photocatalytic and antimicrobial activities of TiO2 nanomaterial are discussed. The results from the literature show that doping of TiO2 shifts the absorption edge to the visible region as a result of the decrease in the bandgap due to the formation of new energy levels in the bandgap. The dopent also acts as a trapping center for electrons and holes, thereby reducing the recombination rate of charge carriers and increasing the photocatalytic and antimicrobial activity of TiO2 nanomaterials. All multidoped TiO2 nanomaterials show higher activity than their undoped, single‐doped, and co‐doped counterparts.
