摘要：

Efficient photocatalysis in the visible light region for degradation of emerging contaminants grasped by quaternary Cu2BaSnS4 (CBTS) quantum dots. Structural, optical, and chemical studies are performed to appraise the physiochemical properties of CBTS. The optimized composition of CBTS with Ba = 0.6 reveals the bandgap of 2.6 eV. High absorption of photons in the visible region and small size made it capable of significant degradation of organic contaminants. The large surface area with sufficient reactive oxygen species disinfected large amounts of E. coli and S. aureus strains. Obtained results reveal that CBTS has excellent potential in photoelectrochemical, photovoltaic, and biological applications.
