Visible light active Cu_(3-x)Zn_xSnS₄ for efficient photocatalytic degradation of brilliant green dye.

ABSTRACT: Copper zinc tin sulfide (Cu_(3-x)Zn_xSnS₄, CZTS) is an eco-friendly, non-toxic, and cost-effective photocatalyst composed of earth-abundant elements, offering a tunable narrow band gap that is ideal for environmental remediation. In this study, CZTS photocatalyst powders with varying Cu:Zn ratios (1:2, 2:1, and 2.5:1) were synthesized using a rapid microwave-assisted method and evaluated for their effectiveness in degrading organic pollutants in water. Structural and optical characterization confirmed the successful synthesis of the kesterite phase of CZTS for all compositions, with optical band gaps ranging from 2.21 to 2.30 eV. Amongst the studied Cu:Zn ratios, CZTS with a 2:1 Cu:Zn ratio exhibits the highest photocatalytic performance, degrading up to 91%
