Abstract
AbstractThe present study demonstrates the preparation of reduced graphene oxide (rGO) incorporated zirconium oxide (ZrO2) nanocomposite by using reflux method. The ZrO2/rGO was confirmed by using UV‐Vis, FT‐IR, XRD, SEM, and EDAX techniques. In photocatalysis examination, the selected Rose Bengal (RB) was degraded effectively using ZrO2/rGO composite (76 %) at 180 minutes which follows first order kinetics. The antioxidant property against 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radicals was found to be 97 % activity with IC50 value of 314.53 mg/mL. Electrode reversibility (EO‐ER), diffusion coefficient (D) and capacitance of rGO, ZrO2 and ZrO2/rGO were measured by cyclic voltammetry method (CV). The electrochemical sensor detection of rGO, ZrO2 and ZrO2/rGO composite were assessed in 1 M NaCl electrolyte using tartaric acid and grape juice green sensors. The prepared electrode material plays a significant role for improving dye removal, electrochemical, antioxidant and sensor detection.
