Functionalization of Cotton by RGO/TiO2 to Enhance Photodegradation of Rhodamine B Under Simulated Solar Irradiation
[EN] Reduced graphene oxide (RGO) and titanium dioxide (TiO2) nanoparticles were immobilized on cotton textile substrates to produce self-cleaning textiles. Varying number of layers of RGO andTiO(2) nanoparticles were coated by a facile method, and their photocatalytic potential was evaluated by mea...
