The development of efficient photocatalysts is very important and desirable in environmental pollution mediation photocatalysts, particularly visible light response catalysts reflects the efficient utilization of solar energy.
In recent years, Copper(I)Sulfate as a photocatalyst has attracted enormous attention due to its great potential in harvesting solar energy for environmental purification and fuel production. The photocatalytic performance of Copper(I)Sulfate strongly depends on its morphology, exposed facets, and particle size. The effects of morphology and orientation of Copper(I)Sulfate on the catalytic performance and the efforts on the stability improvement of Copper(I)Sulfate are reviewed here. This paper also discusses the current theoretical understanding of photocatalytic mechanism of Copper(I)Sulfate , together with the recent progress towards developing Copper(I)Sulfate composite photocatalysts. The crucial issues that should be addressed in future research activities are finally highlighted.
