A visible-light photoredox with homogeneous catalyst-like transition metal complexes and organic dyes shows promising applications in organic synthesis. However, the practical applications of these photocatalysts are hampered by the difficulty of separating and recycling them from the reaction mixtures. In this study, we report the covalent immobilization of Eosin Y on reduced graphene oxide and demonstrate the obtained hybrid can be used as a recyclable photocatalyst with excellent catalytic performances in the aerobic oxidation of α-aryl halogen derivatives.
