Description
Summary:Azo dyes have been widely used for decades as coloring agents in the textile industry. These textile industries discharge their noxious substances into the environment without treating their effluent. Scientists have explored different methods to eliminate harmful dyes such as photocatalysis. In this study, a zinc selenide (ZnSe) nanostructure and its nanocomposite with reduced graphene oxide as ZnSe/rGO were produced using a straightforward hydrothermal technique. The powder x-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) scanning electron microscopy, and other fundamental techniques were employed to measure the crystallinity, surface functionalities, and morphology of the ZnSe/rGO nanophotocatalyst. The optical band gap of the fabricated materials was determined with a UV-Vis spectrophotometer at the range of 200–800 nm. The photocatalytic efficiency of ZnSe/rGO was 94.96% much higher than ZnSe (79.86%) and rGO (88.59%). The carrier's was is examined in terms of its role in facilitating photo-degradation by facilitating the passage of photo-induced charges (electrons and holes) across the complex network of composite materials. The reactive species responsible for the degradation of rhodamine B have been interpreted. This study has the potential to reveal an innovative approach to understanding the effect of a larger interfacial area on the degradation of dyes, while this material can also be employed to purify other water-related issues.
