Year: 2022

Type: preprint

Abstract: Novel Ag encapsulated nanocompositesZnO/Fe2V4O13 (AZF) were synthesized with various wt% of the silver (from 1.0 to 2.5 wt% of Ag) by photo-deposition method using UV-A light. The nanostructure of the AZF was explored by various characterization techniques. Surface functional group was confirmed by FT-IR spectra, the crystalline nature of the material revealed by XRD patterns. Furthermore, surface morphology and optical properties of the composites were analyzed by SEM, HR-TEM UV-DRS and PL respectively. The photoactivity was tested against Methyl Orange (MO) degradation under UV light. The stability of the catalyst was confirmed by reusability measurements. Suitable degradation pathway was proposed based on intermediates obtained during degradation analyzed by GC-MS. Trapping experiments confirmed that super oxide radical anion (O2·–) has been consider as a most active species for this degradation process. Mineralization is confirmed by measurements of chemical oxygen demand (COD).
