biostudies-literatureUnknown12(9)Wu MAccording to the requirements for sustainable development, reclaiming fine chemicals from wastewater under mild conditions is an extremely significant line of research. A low-cost and high-efficiency polydentate chelate- and polymeric Co(ii)-based complex (Co-L)-loaded C₃N₄ photocatalyst (Co-L/C₃N₄) was constructed and used to convert aromatic mandelic acids in wastewater at room temperature. The BET specific surface area increased from 28 m² g^-1 to 68 m² g^-1, indicating its excellent absorptive character. The light absorption range of Co-L/C₃N₄ reached 650 nm, while the band energy reduced to 2.30 eV, which caused a significant enhancement in photocatalytic activity.
