Environmental issues have become more serious these days due to the growth of modern industries. The paper and textile industries, in particular, were heavily dependent on printing discharge dye, which constantly leaked into water ecology constituted a risk public health. Organic wastewater treatment remediation for its associated risks received lot attention lately. This work explored potential g-C3N5 nanostructure as novel photocatalyst malachite green degradation aqueous solution while exposed visible light. nanocomposite was fabricated through an ultrasonicate-assisted technique. A number analysis techniques, such CHNS, XRD, FTIR, UV-DRS, SEM, Electrical, XPS employed verify successful fabrication photocatalyst. At pH 6.5, catalyst dose 0.06 g∙L‒1, with concentration 20 mg∙L‒1, reaction period 90 min, efficiency had been found be 88%. produced hydroxyl radicals (OH•) is considered major scavenger green. above method suggested easy, environmentally friendly practical approach produce excellent photocatalytic 2D nanosheet environmental cleanup.

Abstract Photocatalysis is an efficient technology for the degradation of pollutants. However, it still needs to be improved. In this study, magnetic Z‐scheme FeP/CdS composites heterojunction photocatalysts were prepared by a facile hydrothermal method, and structure, morphology, optical, photocatalytic properties investigated in detail. The efficiency tetracycline hydrochloride (TCH) removal was under different reaction conditions (including FeP CdS ratios, catalyst dosage, hydrogen peroxide consumption, temperature, initial pH). exhibited better catalytic performance compared with pure components. F 1 Cd composite (mass ratio 1:1) achieved 92.7% TCH; moreover, exhibits high stability after five consecutive cycles. capture experiments on active material showed that TCH mainly dominated •OH; however, •O 2 − , e h + played minor role, mechanism revealed combining various characterization techniques. introduction cadmium sulfide formed effective photogenerated carrier transport channel at interface iron phosphide surface, which could accelerate transfer separation photo‐excited /h pairs, thus improving TCH.
