Abstrakt: The current study demonstrates, synthesis of cow urine and honey doped/CeO2 nanocomposite using simple reflux method and inexpensive process. The nanocomposite was characterized and confirmed by X-ray Diffrac-tometer (XRD), Infrared Spectroscopy (IR), Scanning Electron Microscopy (SEM), TEM, Energy Dispersive X-ray spectroscopy (EDS), XPS, and UV-Visible (UV-Vis) spectroscopy techniques. The photocatalysis of methyl orange (MO) dye examined and degraded up to 92% and 93% using both cow urine and honey doped/CeO2 nanocomposite. Electrochemical reversibility (E0-ER), proton diffusion coefficient (D) was analyzed using 3M KCl electrolyte by cyclic voltammetry method (CV). The electrochemical sensor detection of tartaric acid and L-aspartic acid was assessed on developed material. The detection limits for tartaric acid were determined to be 2.09 jM and 3.58 jM, while for L-aspartic acid were 3.49 jM and 3.29 jM, respectively. Cow urine/CeO2 and honey/CeO2 had free radical scavenging activities of approximately 71.91 and 63.95%, respectively. [ABSTRACT FROM AUTHOR]
