研究目的
Investigating the photocatalytic performance of a sandwich-structured MoS2/SnO2/Carbon cloth (MoS2/SnO2/CC) composite for the degradation of RhB dye under visible light.
研究成果
The MoS2/SnO2/CC composite exhibited superior photocatalytic activity for RhB degradation under visible light, attributed to the hierarchical double-layer heterostructure that enhances electron transfer and electron-hole separation. The composite also demonstrated good stability and recyclability, suggesting potential for further applications in photocatalysis.
研究不足
The study focuses on the degradation of RhB dye under visible light, and the recyclability of the photocatalyst was tested up to five cycles. The long-term stability and performance under different environmental conditions were not explored.
