A Critical Study of Cu2O: Synthesis and Its Application in CO2 Reduction by Photochemical and Electrochemical Approaches

Copper oxide (Cu2O) is a potential material as catalyst for CO2 reduction. Cu2O nanostructures have many advantages, including interfacial charge separation and transportation, enhanced surface area, quantum efficiency, feasibility of modification via composite development or integration the favorable functional groups. We cover current advancements in synthesis nanomaterials various morphological dimensions their photochemical electrochemical applications, which complies with physical enrichment activity every application they are employed in. The scope fresh designs, namely composites hierarchy copper nanostructures, ways to improve reduction performance also discussed this review. Photochemical transformations received tremendous attention last few years, thanks growing interest renewable sources energy green facile chemistry. review provides an idea carbon dioxide fixing techniques by using Cu2O-based materials. Carboxylation carboxylative cyclization, yield valuable chemicals such carboxylic acids heterocyclic compounds. Radical ions, induced photo- reactions, well other high-energy organic molecules, regarded essential mid-products reactions CO2. It has been claimed that can be activated form radical anions.
