Abstract
In this present study, we developed a novel bentonite loaded CuWO4 nanoparticles (BEN-CuWO4 NPs) through the simple hydrothermal method. The as-prepared BEN-CuWO4 NPs was systematically characterized by various spectroscopic techniques including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, Field emission scanning electron microscopy (FESEM), High resolution transmission electron microscopy (HR-TEM), DRS-UV visible spectroscopy, Brunauer–Emmett–Teller (BET), X-ray photoelectron spectroscopy (XPS) and Photoluminescence (PL) techniques. For the first time, the BEN-CuWO4 NPs were utilized as a bifunctional catalyst for the photodegradation of Diclofenac sodium (DFS) and electrooxidation of methanol. More distinctively, the BEN-CuWO4 NPs exhibited excellent photocatalytic activity could degrades above 94% DFS solution under visible light illumination with superior stability. Further, BEN-CuWO4 NPs portrayed superior electrocatalytic activity for the oxidation of methanol when compared to the pristine CuWO4. In addition, Impedance studies revealed that the BEN-CuWO4 NPs holds the tremendous dielectrical properties. This present investigation opens a new door way for the synthesis of multifunctional nanostructured materials for practical energy and environmental applications.
