Biological and photocatalytic activities of ZnO NPs over neutral red: Hydrothermal method

Abstract

In this report, it has been proved that the synthesized Zinc oxide NPs (ZnO NPs) are the competent photocatalyst and it has potent antibacterial activity. Herein, we have synthesized the hydrothermal ZnO NPs using zinc sulphate as precursor. The synthesized ZnO NPs subjected for various characteristics such as UV-Visible spectrophotometer. Fourier transforms infrared spectroscopy (FT-IR), Atomic force microscopy (AFM). The absorption maxima (λ max ) were observed at 265 nm & energy band of ZnO NPs was estimated at 3.69 eV. The organic and inorganic compounds confirmed by FT-IR. Morphological study was done using AFM. Further, using Neutral red we have subjected the synthesized NPs for the photocatalytic test and it has been performed well with good degradation of dye as we illuminate the solution to UV light with respect to time. Finally we concluded that synthesized ZnO NPs are good antibacterial activity against two pathogenic bacteria showing the good zone of inhibition. So the synthesized ZnO NPs are excellent in photocatalytic and biological activities.
