Zinc Sulfide (ZnS) based photocatalytic activity has been focused in solar hydrogen production and water treatment process because to their very strong redox reaction. Due to wide visible light range, ZnS becomes a promising semiconductor in formation of photocatalysts. The bandgap energies (Eg) of all prepared samples ZnS NCs and MWCNTs/ZnS nanocomposites were evaluated and Methylene Blue (MB) degradation study occurring of ZnS NCs and MWCNTs/ZnS nanocomposites were evaluated under visible light using UV-visible spectroscopy. The author found that removal rate of MB is greater than 95 percentage in the presence of MWCNTs/ZnS composites photocatalysts after 50 min. Crystalline grain size and structure of photocatalyst were characterized by X-ray Diffraction (XRD) spectroscopy. The enhancement of photocatalytic activity can be associated by many factors like a suitable band gap in visible region, crystalline structure of nanocomposites and particle size in nanometer (nm) of the MWCNTs/ZnS nanocomposites. The suitable photocatalytic reaction and mechanisms of MB degradation also included in this article. |
