Engineering multi-interface Co/Cu co-doped CdS@PCN hybrid architectures for use as high-efficiency visible light driven photocatalysis for the degradation of oxytetracycline

Developing robust and efficient earth-abundant doped metal-sulfide-based hybrid materials for the photocatalytic degradation of pollutants is vital. This study demonstrates the controlled fabrication of multi-interfacial copper and cobalt co-doped CdS and phosphorus-incorporated g-C₃N₄-based hybrid architectures through chemical alloying and a co-precipitation method. The 15% Co/Cu-CdS@PCN-32(hetero) catalyst, with its diverse interfaces and a suitable optical band gap, exhibited excellent 96. 45% in 40 minutes with a rate constant of 0.0831 min^-1. Moreover, the photocatalyst has shown excellent durability. This study has the potential to facilitate the development of a multifunctional composite material by combining hybrid component interfaces.
