Abstract

The fabrication of WO2/α-ZnMoO4 nanocomposite using a novel chemical aqueous technique is described in this research. This treatment is mild, easy to use, affordable, and successful. The samples were described using XRD, FT-IR, SEM, EDX, and UV-DRS as they were created. The WO2/α-ZnMoO4 is seen in the visible portion of the DRS (Diffuse Reflectance Spectroscopy). The structural and morphological features of the generated WO2/α-ZnMoO4 nanocomposite were examined using SEM. The photocatalytic activity of WO2/α-ZnMoO4 nanocomposite for the Rose Bengal degradation was investigated in depth under visible light. The WO2/α-ZnMoO4 nanocomposite had the best photodynamic performance (59 percent to 96 percent of RB degradation). Adsorption of Rose Bengal came next. Using a kinetic pseudo-first order kinetics, the samples' exceptional stability was tested four times under visible light using photodegradation RB. The relationship between structure of the WO2/α-ZnMoO4 nanocomposite and photocatalytic activity, are investigated. As a result, the method of preparation throws light on the photocatalytic destruction of organic pollutants using WO2/α-ZnMoO4 nanocomposite.
