Photogenerated electron–hole separation-driven CO2 reduction coupled with tetracycline oxidation over a LaMnO3 nanoparticles/oxygen-etched g-C3N4 heterojunction: complementary effects brought by proton transfer

The complementary effects resulting from the combination of LaMnO 3 /oxygen-etched g-C 3 N 4 due to proton transfer enhance the photocatalytic reduction of CO 2 coupled with the oxidation of tetracycline.
