研究目的
Investigating the enhancement of photocatalytic performance of Ag3PO4 through decoration with Co3O4 nanoparticles under solar-light-driven conditions.
研究成果
The Co3O4/Ag3PO4 photocatalyst prepared by in-situ synthesis method showed significantly improved photocatalytic activities for degrading MB and BPA under visible light irradiation, with enhanced stability and efficiency. The heterostructure formed between Ag3PO4 nanoparticles and Co3O4 nanosheets facilitates effective charge separation and improves photocatalytic performance.
研究不足
The study faces challenges such as photo-corrosion phenomenon and slight solubility in water, which may limit the practical application of the photocatalyst.
