Visible-light induced photo catalytic response of MWCNTs-CdS composites via efficient interfacial charge transfer
In the present manuscript visible light induced photo catalytic performance of MWCNTs intercalated CdS nanocomposites has been studied. Methylene blue (MB) organic dye has been used as a probe for determination of catalytic performance. XRD spectra confirms hexagonal structure with average particle size distribution between 10 and 20 nm. SEM images confirm close contact between MWCNTs and CdS with quasi spherical shape. UV–Vis spectra confirms enhanced optical absorption and photocatalytic adsorption. The observed photocatalytic activity was enhanced by 2.6 times attributed the heterojunction between MWCNTs and CdS may lead an enhanced separation efficiency of photo generated e/h pairs.
