Self-assembling reduced graphene oxide and TiO2-based materials for solar photocatalytic wastewater treatment

In this study, we employed a simple and eco-friendly method to prepare self-assembling self-standing membranes of: i) graphene oxide (GO), ii) reduced GO (rGO), iii) rGO and TiO2 (rGO-TiO2). We tested the three membranes for adsorption and solar photodegradation of Imidacloprid in water, obtaining evidence of a remarkable solar photocatalytic activity of rGO. To the best of our knowledge, no other photocatalytic rGO self-standing membranes have been reported yet.
