Fabrication and self-cleaning performance of RGO/(Si, Mo)-codoped TiO2 thin films for architecture environment decontamination application.

Abstract

Self-cleaning is a potential technique in architecture environmental decontamination. We report t The fabrication and self-cleaning property enhancement of the TiO2 hybridizing reduced graphene oxide (RGO) and codoping Si and Mo. The films were deposited by a sol-gel dip-coating process. The self-cleaning properties were characterized by photocatalytic activity, photoinduced super hydrophilicity, and conductivity. Incorporating RGO provided an efficient interface-induced effect, and doping Si and Mo enhanced this effect. Thus, the hybrid films showed remarkably enhanced self-cleaning performances. The transparency of the films also did not affected by RGO shown high transparent when RGO is added in the condition of the doping Si and an appropriate amount of Mo.
