Facile synthesis and characterization of a visible light-active ternary TiO2/ZnS/g-C3N4 heterostructure for multipollutant degradation

This study revolves around assessing the effectiveness of a ternary heterostructure, TiO2/ZnS/g-C3N4 (1:1:1 w/w mixture), synthesized through a facile hydrothermal process for the simultaneous degradation of both single and mixed pollutants under visible light. The advanced microscopic and spectroscopic techniques (FESEM, TEM, FTIR, UVDRS, BET) employed confirmed its enhanced photocatalytic performance. The UV–Vis DRS analysis unveiled the synthesized heterostructure's superior band gap energy of 2.81 eV compared to pristine TiO2, leading to enhanced light absorption within the visible spectrum. Under visible light exposure, the ternary TiO2/ZnS/g-C3N4 heterostructure exhibited impressive efficacy, removing approximately 90
