Cadmium sulphide (CdS) nanostructures were synthesized via a simple chemical precipitation method by
using Mercaptoethylamine hydrochloride (MEA) as a capping agent. Fine tuning of the nanosized CdS
material was carried out by controlling the amount of the capping agent. The synthesized CdS nanostructures
were characterized by UV–Vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy
(SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), and UV–
Vis diffuse reflectance spectroscopy (DRS). Optical absorption spectroscopy was mainly used to measure
the band gap and size of the CdS nanostructures. The photocatalytic activities of the synthesized samples
were investigated for degradation of methylene blue (MB) under blue LED (3 W) and solar light
irradiation.
