Ternary heterogeneous Z-scheme photocatalyst TiO₂/CuInS₂/OCN incorporated with carbon quantum dots (CQDs) for enhanced photocatalytic degradation efficiency of reactive yellow 145 dye in water.

ABSTRACT: This study delves into the advanced integration of a ternary heterogeneous Z-scheme photocatalyst, TiO₂/CuInS₂/OCN (OCN: O-g-C₃N₄), with carbon quantum dot (CQD) to improve the degradation efficiency of reactive yellow 145 (RY145) dye in water. Through a systematic examination, we elucidated the photocatalytic mechanisms and the role of radicals, electrons, and holes in the treatment process. Our findings revealed that this novel catalyst integration significantly boosted RY145 degradation efficiency, achieving 98.2%, which is markedly higher than the efficiencies which could be achieved using TiO₂/CuInS₂/OCN alone. Moreover, the TiO₂/CuInS₂/OCN/CQD photocatalyst demonstrated superior rate performance o
