Visible Light Active Photocatalysts

What is it about?

A ball-flower like CuS and CdS nanoflake like photocatalysts were synthesized. The 1%, 2% and 3% CuS/CdS nanocomposites were prepared by the wet impregnation method. Among various composites, 1% CuS/CdS composite exhibited a higher photocatalytic activity for the degradation of methylene blue under visible light irradiation. The enhancement of 1% CuS/CdS composite photocatalyst is attributed to the efficient charge carrier separation of the electron-hole pairs. The PL and EIS studies were carried out to show that 1% CuS/CdS nanocomposite was efficient for photocatalytic degradation of methylene blue. Our results indicate that CuS acts as an electron acceptor and effectively prevents the recombination of photogenerated charge carriers. The data presented in this study may be useful for the development of a low-cost and efficient catalyst for the photocatalytic degradation of organic pollutants in aqueous environment.
