Description
Summary:The present study dealt with the facile synthesis of Tulsi honey-doped cerium oxide (TH/CeO2) through a reflux method. The sample was characterized using UV-Visible, FTIR, TEM, and XRD techniques. The photocatalytic studies were implemented on Rh-B (Rhodamine B) dye using TH/CeO2 and showing 95% degradation after 80 minutes, following a first-order kinetic rate of the reaction and with a half-life (t1/2) period of about 42.58 minutes. The cyclic voltammetry method was used to analyse the redox behaviour of TH doped CeO2 in a 1 M KCl solution using a nickel mesh electrode, indicating a significant improvement in electrochemical properties such as capacitance (Csp), diffusion coefficient (D), and reversibility (ER). The prepared nanocomposite was used to detect the sensor activity of Hg+2 and Pb+2 ions using cyclic voltammetry. Here, Hg+2 and Pb+2 sensors demonstrated better sensing properties using the prepared material. The generated TH/CeO2 exhibited 88% free radical scavenging activity using 2,2-diphenylpicrylhydrazyl (DPPH) free radical, with IC50 value of 339.449 mg/mL.
