Abstract

Because of the excessive use of fossil fuels, CO₂ emissions into the environment are increasing. An efficient method of converting CO₂ to useful carbonaceous products in the presence of light is one way to address the issues associated with energy and environmental remediation. In₂S₃/WS₂ heterostructure has been fabricated using the efficient hydrothermal method. The results of structural, morphological, optical, and photo/electrochemical characterization confirm the formation of a hierarchical, layered heterostructure of type-II. Enhanced photocatalytic activity is observed in InS/WS heterostructure compared to pristine In₂S₃ and WS₂. InS/WS heterostructure exhibit higher photocatalytic activity than pure In₂S₃ and WS₂. For 12 h, photocatalytic CO₂ reduction produces 213.4 and 188.6 μmol of CO and CH₄, respectively. Furthermore, the photocatalytic ability of the synthesized materials to degrade different parabens (Methyl: MPB, Ethyl: EPB, and Benzyl: BPB) under visible radiation was evaluated. Under optimized conditions, the InS/WS heterostructure degraded 88.6, 90.4, and 95.8% of EPB, BPB, and MPB, respectively, in 90 min. The mechanism of photocatalysis was discussed in detail. MCF-7 cell viability was assessed and found to exhibit low mortality in InS/WS treated MPB aqueous solution. InS/WS heterostructure could improve the fabrication of more sulphide-based layered materials to combat environmental pollution.
