MoS2/Ag nanocomposites for electrochemical sensing and photocatalytic degradation of textile pollutant

MoS2/Ag nanocomposite has been successfully synthesized by hydrothermal–wet chemical method. MoS2/Ag nanocomposites were characterized by powder X-ray diffraction (XRD), transmission electron microscopy and selected area electron diffraction. XRD patterns confirmed the presence of MoS2 and Ag phases in the synthesized composite. Photocatalytic ability of the nanocomposite evaluated against methylene blue (MB) and Novacron Red Huntsman (NRH) dye under normal light source for 80 min. Catalytic loading (1 g/L) lead to maximum degradation rate of 77.9% and 77.5% for MB and NRH dye respectively. Nanocomposites exhibited sensing ability against nitrobenzene. The sensing capability was evaluated using cyclic voltammetry electrochemical technique. Mechanisms of the photocatalytic activity and electrochemical sensing are also explained herewith.
