Application of TiO2-based photocatalysts to cementitious materials is the subject of many researches in the last two decades. The application of TiO2-based photocatalysts to cementitious materials is mainly aimed at achieving two goals, the depolluting action due to the oxidation of NOx present in the atmosphere to NO3- and the self-cleaning effect of the photocatalytic cement surface. As regard to depollution, NOx emission reduction is a focus of environmental regulations. In Europe, the values are specified in the European Union (EU) directives (e.g., 2008/50/EC).

The invention relates to photocatalytic compositions, and, more particularly, but not exclusively, compositions comprising a catalyst photo and a graphene material.

The invention allows:

- Pollution reduction

- Surface self-cleaning
