Design of graphene-based TiO2 photocatalysts - A review

Abstract

There is a recent increase in the interest of de- signing high-performance photocatalysts using graphene- based materials. This review gathers some important aspects of graphene–TiO 2 , graphene oxide–TiO 2 , and reduced gra- phene oxide–TiO 2 composites, which are of especial rele- vance as next generation photocatalysts. The methods used for the preparation of these materials, the associated mech- anistic fundamentals, and the application of graphene-based composites on the photocatalytic degradation of pollutants are reviewed. Some structural, textural, and chemical prop- erties of these materials and other photo-assisted applica- tions, such as hydrogen production from water splitting and dye-sensitized solar cells, are also briefly included
