Article Abstract
CuO-based composites for photocatalysis have been extensively explored owing to their promising application in solving environmental and energy problems. At present, the research on photocatalysis is focused on improving the photocatalytic performance of materials. It has been reported that adjusting the morphology and size of CuO can effectively improve its photocatalytic property. However, photocorrosion is still an inevitable problem, which hinders the application of CuO in photocatalysis. The strategies of constructing heterogeneous nanostructures and ion doping can significantly improve the light stability, light absorption capacity and separation efficiency of electron-hole pairs. CuO-based composites exhibit superior performances in degrading organic matter, producing hydrogen, reducing CO and sterilization. Therefore, the construction of multi-materials will be one of the future directions in their photocatalytic application. This review summarizes the recent strategies for enhancing the photocatalytic activity of CuO by analyzing different CuO-based photocatalysts, and the charge transfer pathway is further discussed in detail. Finally, several opportunities and challenges in the field of photocatalysis are illustrated.

This study explores the influence of Fe ion incorporation on the oxygen-evolution reaction (OER) in alkaline media, utilizing CuO-based materials. Instead of developing an efficient and stable OER catalyst, this research investigates two distinct CuO variants: one with Fe ions adhered to the surface and another with Fe ions integrated into the CuO lattice. By employing a variety of analytical techniques, the study demonstrates that the CuO variant with surface-bound Fe ions (referred to as compound 1) exhibits significantly enhanced OER performance compared to the variant with internally embedded Fe ions (referred to as compound 2).
