Analysis of the Photocatalytic Activity and Adsorption of CuS Nanoparticles Synthesized by Chemical Route for the Degradation of Organic Contaminants

and using a low catalyst dose, showed promising results. Samples with lower sulfate content reached ∼78% degradation, while those with 0.20 M thiourea and 0.15-0.20 M sulfate achieved up to 99%. Mesoporous and macroporous structures (3.85-50 nm) promoted adsorption without hindering photocatalytic efficiency, indicating that, in certain samples, the combined morphological and electronic features enhanced dye removal.
