Tunable Carrier Transfer of Polymeric Carbon Nitride with Charge-Conducting CoV₂O₆∙2H₂O for Photocatalytic O₂ Evolution.

ABSTRACT: Photocatalytic water splitting is one of the promising approaches to solving environmental problems and energy crises. However, the sluggish 4e^- transfer kinetics in water oxidation half-reaction restricts the 2e^- reduction efficiency in photocatalytic water splitting. Herein, cobalt vanadate-decorated polymeric carbon nitride (named CoVO/PCN) was constructed to mediate the carrier kinetic process in a photocatalytic water oxidation reaction (WOR). The photocatalysts were well-characterized by various physicochemical techniques such as XRD, FT-IR, TEM, and XPS. Under UV and visible light irradiation, the O₂ evolution rate of optimized 3 wt% CoVO/PCN reached 467 and 200 μmol h^-1 g^-1, which were about 6.5 and 5.9 times higher than
