Review of Recent Developments in the Fabrication of ZnO/CdS Heterostructure Photocatalysts for Degradation of Organic Pollutants and Hydrogen Production

“…Recent research has revealed that ZnO/CdS heterostructures outperformed pristine ZnO and CdS nanostructures in terms of photocatalytic performance under visible-light irradiation [37][38][39]. Because of their distinctive electronic band structure, changed bandgap, and high charge transfer efficiency, ZnO-based semiconductor nanostructures have been employed as efficient photocatalytic materials for the breakdown of organic pollutants and chemical processes such as hydrogen or oxygen synthesis [40,41].…”

“…The scientific frontiers of electrocatalysis and photocatalysis have recently gained a lot of attention. The electrochemical reactions in heterogeneous catalysis take place at the electrode-electrolyte interface, where the electrode serves as both a catalyst and an electron donor/acceptor [37,45]. Therefore, ZnO/CdS heterostructures have been considered as the most researched materials for the photocatalysis process owing to their enhanced optical and catalytic properties compared to the bare ZnO and CdS.…”

“…In this context, the use of ZnO/CdS heterostructures in photocatalysis has drawn considerable attention from a wide range of researchers and academicians since it provides an effective and environmentally friendly solution to wastewater management [48,49]. Recently, He et al synthesized binary CdS/ZnO heterostructures by a facile aqueous chemical process and found that the optimized CdS/ZnO heterostructures (CZ-3) exhibited a superior hydrogen production rate and dye degradation efficiency than the bare ZnO and CdS [37]. According to Lu et al, the hydrothermally grown ZnO/CdS heterostructures on FTO substrate have shown a 105 times higher photocatalytic hydrogen production rate (7669 µmol/g/h) than pure ZnO with a highest cyclic stability of 92.02% after 5 cycles for the optimized sample (ZS3) [47].…”
