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

This study introduces a simple one–step in situ calcination strategy for fabricating a heterojunction of perovskite–type LaMnO3 nano–particles/oxygen–etched graphitic carbon nitride (OE–g–C3N4) to enhance photogenerated charge separation and suppress electron–hole...
