Abstract

The present work narrates the photocatalytic behaviour of TiO2/CdS nanocomposites for the degradation of the organic dyes brilliant green and methylene blue under solar light irradiation. For this process, TiO2 loaded with different concentrations of CdS was prepared through a sol–gel approach and the prepared products were studied for their structural, optical and morphological characteristics. The degradation details of the studied composites reveal that TiO2 loaded with an optimum level of CdS is known to have outstanding catalytic activity due to its higher BET surface area, rod-like morphology and low charge transfer resistance.
