Graphene quantum dots (GQDs) are explored as a green sensitizer to functionalize ZnO nanowire arrays (GQDs@ZnO NWs) by covalently bonding GQDs on ZnO NWs that are grown on F-doped SnO2 glass and modified with amine groups. Using a Pt counter electrode, the GQDs@ZnO NWs photoelectrodes exhibit enhanc...
