“…The survey scan of pristine SnS 2 as shown in figure 3(a) revealed the presence of Sn and S elements. The presence of impurity elements (C and O), which are observed in general, is attributed to the existence of adventitious contamination species or residual precursor materials during the deposition process [54]. Whereas, Cu-doped SnS 2 thin films have an additional peak corresponding to Cu, confirming the successful incorporation of Cu into SnS 2 .…”

Tin sulfide (SnS2) is a material known for its effective photocatalytic activity due to its affordability and wide light spectrum response. To enhance and optimize its optical and chemical characteristics, doping is a straightforward approach that can improve its photocatalytic efficiency. This work focuses on the effect of Cu doping on the structural, optical, and photocatalytic properties of the thin films prepared by the spray-coating approach. XRD confirms the hexagonal SnS2 structure. As the amount of Cu added increases, the crystallite size decreases while dislocation density rises. The effective band gap is in the range of 1.9-2.2 eV. SEM image reveals a variety of morphologies, and the porosity is reduced with increasing Cu doping. Furthermore, the FTIR study confirm the Sn-S bond present at 753 cm-1. EPR studies reveal the existence of sulphur vacancies in Cu-doped SnS2. Mechanical properties were also affected, with an observed decrease in microhardness as the dopant concentration increased. The photocatalytic activity of the samples is studied by photocatalytic degradation of malachite green and Congo red dyes under visible light irradiation. Additionally, their antibacterial effect against Escherichia coli was examined. This study shows that an optimal amount of Cu doping can significantly increase the photocatalytic performance of SnS2 for efficiently decomposing organic pollutants and enhance antibacterial activities.
