MoO3-PVA films hybridized with silver and copper nano-particles mediated by microwave heating were studied for energy applications. The composites films were characterized by Infra-red (FTIR), Thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), UV–Visible spectroscopy and X-ray diffraction (XRD). The crystallite size from XRD peak width was estimated to be about 60–65 nm in the nanocomposite. The electromagnetic interference (EMI) shielding efficiency of so generated composites showed that metal containing composites have higher efficiency in X-band. The EMI study showed promising scope for application in low shielding requirement areas. The so-generated silver containing hybrid system resulted in visible light tunable band-gap (2.34–2.81 eV). Ag-MoO3-PVA (Sample PV-C) showed more than 90 % photocatalytic degradation of methylene blue dye. © 2023 Elsevier B.V.
