Structural, Morphological, Optical, Electrical and Agricultural Properties of Solvent/ZnO Nanoparticles in the Photodegradation of DR-23 Dye

Nowadays, in the field of modern technology, application of nanoparticles has an active role in basic and applied sciences. Herein, optimization of the shape and size synthesis of ZnO nanoparticles has been done by using different solvents, namely, isopropyl alcohol (IPA) and triple-deionized water (TDW). The influence of different solvents on the structural, morphological, optical, electrical and thermal properties has been analyzed. The observed morphology was in the form of a ZnO nanosphere with grain size in the range of 20-25 nm. Electrical properties confirmed that the prepared sample can be used for fabrication of charge storage devices with a capacitance range of 7-9 mu F. Thermal study revealed that the prepared nanoparticles are useful for application in solar cells. ZnO nanoparticles prepared with TDW (solvent) have better optical properties than IPA, so the photocatalytic properties of synthesized nanoparticles (prepared by TDW) were investigated under ultraviolet (UV) light using direct red-23 (DR-23) dye. Almost complete photodegradation of DR-23 dye was observed within 60 min. Kinetic study reveals the rate constant for photodegradation of DR-23 dye was found to be 0.0613 min(-1). This degraded water is further used for agricultural purposes.
