Enhanced photocatalytic degradation activity over TiO2 nanotubes co-sensitized by reduced graphene oxide and copper(II) meso-tetra(4-carboxyphenyl)porphyrin
CuTCPP and rGO are helpful to induce interfacial charge transfer at surface junction.
•
CuTCPP and rGO are favorable for enhancing co-photocatalytic activity.
•
A deeper insight into the co-photocatalytic mechanism is put forward.
•
The photocatalyst are proven to be effective and chemically-stable catalysts.
