This work describes the hydrothermal method for synthesizing a novel nanocomposite: Nickel -doped Cerium oxide on reduced graphene (Ni-CeO2/rGO). The resulting material exhibits exceptional electrocatalytic behavior, showing promise supercapacitor applications. Phase morphology, elemental analysis, surface area and oxidation state were confirmed by powder X-ray diffraction studies (PXRD), Raman spectrum, High Resolution Transmission Electron Microscopy (HRTEM), Field Emission Scanning (FESEM) Energy Dispersive (EDX), Brunauer-Emmett Teller (BET) XPS respectively. Electrochemical analysis involving cyclic voltammetry (CV), Galvanostatic charge/ discharge, impedance spectroscopy (EIS). specific capacitance is 262.1Fg-1, 504Fg-1, 728Fg-1 CeO2, CeO2/rGO, Ni-CeO2/rGO it depicts its suitability energy storage. study establishes nanocomposite as highly effective advanced storage

Abstract The present study demonstrates the preparation of reduced graphene oxide (rGO) incorporated zirconium (ZrO 2 ) nanocomposite by using reflux method. ZrO /rGO was confirmed UV‐Vis, FT‐IR, XRD, SEM, and EDAX techniques. In photocatalysis examination, selected Rose Bengal (RB) degraded effectively composite (76 %) at 180 minutes which follows first order kinetics. antioxidant property against 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radicals found to be 97 % activity with IC 50 value 314.53 mg/mL. Electrode reversibility (E O ‐E R ), diffusion coefficient (D) capacitance rGO, were measured cyclic voltammetry method (CV). electrochemical sensor detection assessed in 1 M NaCl electrolyte tartaric acid grape juice green sensors. prepared electrode material plays a significant role for improving dye removal, electrochemical, detection.

The current research presents an environmentally friendly reflux approach for synthesising a nanocomposite with multifloral honey (MH) doped cerium oxide (CeO2). formed material was analysed using X-ray diffraction (XRD), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET), Zeta potential (PZC), Fourier transform infra-red spectroscopy (FT-IR), and UV-visible (UV-Vis). Optical property such as reflectance, refractive index, band gap, conductivity, dielectric constant were examined MH-doped CeO2 analysis revealed supportive results. electrochemical evaluation showed specific capacitance (Csp) of around 149 Fg−1 diffusion coefficient 1.49 × 10−4 3 M KOH solution. composite also better sensing properties towards lead nitrate, cow urine mercury chloride sensors. First-order rate kinetics described in photocatalytic investigation catalyst, showing excellent degradation performance methyl violet (MV) Congo red (CR). Furthermore, the synthesised compound's IC50 value 200.37 mg/mL 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging demonstrated 79.59% antioxidant activity.
