Development of Coriander Honey loaded CeO2 for cyclic voltammetry, chemical sensor, dye purification, and antioxidant properties

Abstract

BackgroundThe present study was involved the CH-doped CeO2 NPs using low-cost and environmental friendly like coriander honey (CH). Besides, CH-doped/CeO2 NPs was employed as sensor, electrochemical, and water treatment activities of the synthesized NPs. MethodsThe coriander honey was used as a supporting materials to synthsized CH-doped/CeO2 NPs by simple reflux method. Various spectroscopic techniques were used to analysed including UV-Vis, XRD, IR, SEM, and EDAX. Significant FindingsIt is exposed that was employed as the electrochemical analysis was performed using cyclic voltammetry with 3M KOH, which yielded a specific capacitance of 155.7 Fg−1 and proton diffusion coefficient results of about 1.89×10−4. The study also examined the composite material's sensing properties using some chemicals like mercury chloride, lead nitrate, and cow urine (gomutra) is an eco-friendly liquid, and found them to perform well within the oxidation and reduction potential range. Photocatalytic studies were conducted using methyl violet (MV) and Congo red (CR) dye, which showed a high degradation rate of 95.1 and 78.7%, respectively, demonstrating first-order kinetics with the coriander honey/CeO2 NPs composite. Finally, the antioxidant property of the composite material was tested using the free radical scavenging method with DPPH (2,2-diphenyl-1-picrylhydrazyl), yielding an activity of 79.37% and an IC50 value of 5581.157mg/mL.
