An Investigation on Kinetics of Photo Catalysis, Characterization, Antibacterial and Antimitotic Property of Electrochemically Synthesized ZnS and Nano Photocatalysts

Abstract

Zinc sulphide is one of the commercially important II-VI semiconductors having a wide band gap, rendering it a very attractive material for optical application especially in nanocrystalline form. Nanocomposites of ZnS and ZrS 2 /ZnS were prepared by simple electrochemical method; their photocatalytic properties had been investigated. The structure, composition and optical property of the product were characterized by X-ray diffraction (XRD), FE-SEM (EDAX), UV-VIS and IR techniques. The UV-VIS spectra exhibited a blue-shift with respect to that of bulk material due to quantum confinement effect. Kinetics of photocatalytic degradation of Indigo Carmine dye has been studied. The photocatalytic decolourization of the dye follows first order kinetics. The antimitotic and antibacterial activity of these nanoparticles was investigated.

“…Nanomaterial is the most intense research subject of material scientists due to their good physical and chemical properties. Electrochemical methods were proven to have some additional advantages over chemical methods in the synthesis of various nanomaterial, especially metal nanocomposites [1] [2] [3]. Various types of coagulants have shown potential applications in wastewater treatment.…”
