Abstract
In this study, we report the synthesis of two CdS@TiO2 nanocomposites (CT1 and CT2) by two-step low temperature solvothermal decomposition method using two different stoichiometric combinations between CdS and TiO2 nanoparticles (NPs). CdCl2(3-chlorobenzaldehyde thiosemicarbazone)2 was used as a molecular precursor to obtain CdS NPs, whereas titanium isopropoxide was used to obtain TiO2 NPs. The as-prepared CT nanocomposites were characterized by powder X-ray diffraction, field emission scanning electron microscopy, Raman spectroscopy, transmission electron microscopy and X-ray photoelectron spectroscopy to evaluate their structures and properties. Further, these nanocomposites were used for the photocatalytic degradation of rhodamine B under solar light irradiation. It is found that CdS@TiO2 (CT1) nanocomposite shows highest degradation efficiency of 98.74% within 60 min as compared to bare TiO2 NPs which shows only 66.40% degradation efficiency. The enhanced photocatalytic efficiency due to charge transfer properties of bare NPs and CT nanocomposites was further investigated by electrochemical analysis and photoluminescence studies.
