This work investigates the synthesis, characterization, and photocatalytic activity of Ag3PO4/SnO2 nanocomposites for Isoproturon degradation. The Ag3PO4/SnO2 nanocomposite was synthesized using hydrothermal method. Nanocomposite was characterised using various analytical techniques like PXRD, FTIR, SEM, UV-DRS, and XPS. Furthermore, elemental mapping validated the uniform distribution of O, P, Ag, and Sn throughout the material. The Ag3PO4/SnO2 nanocomposite demonstrated improved efficiency in Isoproturon degradation, achieving over 97% degradation within 120 minutes of light irradiation which is higher than pristine SnO2 (25% degradation) and Ag3PO4 (41% degradation). This significant improvement compared to its precursors is attributed to the heterojunction formation and the increased surface area of the nanocomposite. HRMS was utilized to analyse the degradation products. The study validates the mechanistic aspects and synergistic effects responsible for the enhanced photocatalytic performance, highlighting the potential of Ag3PO4/SnO2 nanocomposites for environmental remediation applications, particularly pesticide degradation.
