Abstract
CdS nanoparticles decorated CuS microflower-2D graphene hybrids (CdS/CuS-MF/G) were synthesized in environmentally friendly route and applied as photocatalysts. Composites were characterized with various techniques to investigate their morphology, structure, and optical properties. Photocatalytic activity of samples was evaluated by methyl orange (MO) degradation, and the sample reached photocatalytic efficiency of 84.8% in 120 min. The cause of enhanced photocatalytic activity was attributed to heterojunction in CuS/CdS and excellent electronic conductivity of graphene, which formed three-level electron transfer process. This results in enhanced photogenerated charge carrier separation in composites. Due to high photocatalytic efficiency, as-prepared photocatalyst could encourage further development regarding its application in photocatalytic water treatment.
