Abstract

A precipitation-deposition mixture of manganese dioxide and lead sulphide was produced with lead sulphide concentrations ranging from half a milligramme (0.5 PbS) to one and a half milligrammes (1.5 PbS). Testing the metal with different instruments was the next stage. Some of the methods that were used include photoluminescence spectroscopy, SEM, ED-X-ray spectrometry, BET-surface area, and UV-visible diffuse reflectance spectra. Testing the photocatalytic activity using methylene blue dye revealed that 1% PbS/MoS2 outperformed both 0.5% and 1.5% PbS/MoS2. We looked at the photocatalytic activity as a function of pH and catalyst dose, among other factors. Light activates the PbS-MoS2 combination, which effectively breaks down methylene blue (MB) dye.
