Summary: The synthesis of optoelectrically enhanced nano-materials should be continuously improved. The porous zinc oxide (ZnO) and copper-doped ZnO nanocomposites (NCs) were successfully synthesized by the time-and energy-efficient solution combustion synthesis (SCS) approach. The doping and heterojunction strategy improved the optoelectric properties of the NCs more than the individual constituents, enhancing the charge transfer and optical absorption capabilities. The SCS approach offers a less expensive and more efficient method for various applications, such as catalysis and sensors.

Summary: This review discusses the recent advances in the synthesis approaches, fundamental properties, and photocatalytic activity of Cu3N nanostructures. The study found that the synthesis conditions play a crucial role in the shape and size control of Cu3N. Cu3N nanostructures exhibit a narrow bandgap and excellent optical properties, and the presence of Cu and N vacancies on the surface of the nanoparticles contributes to their photocatalytic dye-degradation potential. Additionally, combining plasmonic nanoparticles with other photocatalysts enhances the efficiency of Cu3N.
