| contents | This study attempts to break down Rhodamine dye with ZnWO4@CN nanocomposites for environmental use. The nanocomposites were made using a simple hydrothermal process and examined for optical, structural, and morphological properties. XPS, SEM-EDX, UV-DRS, and PL are examples. RhB dye degradation in water was employed to test photocatalytic activity. The study found that ZnWO4@0.5 % CN has superior photocatalytic performance compared to pure ZnWO4, ZnWOâ'"@0.1% CN, and ZnWO4@1.0 % CN nanocomposites. The synergistic effect results from efficient photoinduced electron-hole pair separation and transfer. As an excellent electron conductor, activated carbon increases charge separation and extends charge carrier life. Photocatalytic experiments indicated ZnWO4@0.5 % CN nanocomposites destroyed 97% RhB dye in 150 minutes. Quenching investigations confirmed that the degradation kinetics followed a pseudo-first-order model, indicating that reactive oxygen species (ROS) formed efficiently and abundantly caused dye degradation. |
