TiO2/carbon composite nanomaterials for photocatalysis

Abstract

Facing with the urgent environmental issues, the scientists have broadly explored TiO2 nanomaterials. In consideration of its narrow adsorption region, some modifications need to be done on TiO2 nanomaterials. Recently, nonmental carbon materials have been addressed with much attention in photocatalysis, for instance, carbon dots, carbon nitride (C3N4), graphene, etc. In this chapter, TiO2/carbon composites are specifically reviewed, including carbon dots–TiO2 nanomaterials, g-C3N4/TiO2, and graphene/TiO2 nanomaterials. Besides this, their detailed preparation methods are clarified as well and then accompanied by various applications, such as photocatalytic degradation of organic pollutants, water splitting, photoelectrochemical cell, photocatalytic CO2 reduction, and disinfection of bacteria.
