Hierarchical MoS 2 –SnS 2 @g–C 3 N 4 Nanocomposite as an Efficient and Sustainable Material for Environmental Remediation

Conquering simple and efficient photocatalyst materials for organic pollutant degradation is a central determinant in environmental applications. Because of its exemplary optical and electrical properties, molybdenum disulphide—tin disulphide@graphitic carbon nitride (MoS2–SnS2@g–C3N4) has garnered much attention in this research. The molecular structure, elemental composition, and optoelectrical characteristics of MoS 2 –SnS 2 @g–C 3 N 4 were examined by X-ray diffraction pattern (XRD), X-ray photoelectron spectroscopy, and Ultraviolet-Visible diffuse reflectance spectroscopy (UV–Vis DRS). Transmission electron microscopy (TEM) was used to thoroughly investigate the morphology of MoS 2 –SnS 2 @g–C 3 N 4 , which disclosed a 2D sheet-like structure. The degradation efficiency of as-synthesized samples was studied using model pollutant (Methylene blue), where MSSG-3 heterojunctions exhibited better photocatalytic efficiency compared to MSSG-2, MSSG-1 and MSS. Furthermore, the antimicrobial efficacy of the prepared MSSG-3 was analyzed towards two strains of bacteria, Streptococcus mutans ( S. mutans ) and Enterococcus faecalis ( E. faecalis ). Compared to the conventional antibiotic as a positive control, the MSSG-3 NCs exhibit more excellent antimicrobial properties against S. mutans and E. faecalis . The antibacterial ability of MSSG-3 NCs has a zone of inhibition range of 26.3 mm and 24.3 mm, respectively. The innovative MSSG-3 NCs outstanding qualities made them an attractive contender for various sectors, particularly for eradicating textile colours from wastewater and antimicrobial properties in environmental applications.
