چکیده

This work reveals a sol–gel approach for synthesis of silver doped magnesium oxide (Ag:MgO) incorporated in PVC matrix to give Ag:MgO/PVC nanocomposite. On glass substrate three different percentages (3,7, and 10%) were deposited by spin coating method. film nanocomposites characterized using AFM, UV–Vis, XRD FTIR analysis. The results revealed the formation Ag MgO nanoparticles with two phases (MgO metallic Ag) average size equal 31.5,22.29, 23.77, 29.68 nm. direct band gap energy pure MgO/PVC was 4.1 eV 3.85 respectively. value changes from eV, 3.75 3.71 3.69 increasing Ag:MgO concentration(3–10%). Atomic force microscopyalso shows change roughness percentage. photocatalytic activity this nanocomposite evaluated methylene blue (MB) dye under UV light irradiation. result demonstrated good potential films MB degradation suitable reaction proposed mechanism. kinetic studies rate constant 6.25 × 10–3 min−1 10% thin films.
