Solar photo-degradation of aniline with rGO/TiO 2 composites and persulfate.

The solar photodegradation of aniline using reduced graphene oxide-based composites (rGO/TiO2) and different electron acceptors such as H2O2 and persulfate (PS) has been studied. To this end, an innovative self-sufficient drum reactor (operating with solar irradiation and artificial UV light) has been employed. The role of radicals and the new graphene morphology is evaluated. Finally, changes in the degradation/mineralization mechanism are explained according to intermediates evolution (obtained from mass spectroscopy).
