Multifaceted Ag-Mo-WO3 for superior photocatalytic, luminescence, sensing and antioxidant activities
Discharge of hazardous industrial effluents cause environmental pollution and induce health related problems in living organisms. Multifunctional Ag-Mo-WO3 NPs were developed via green combustion method using Mentha spicata as a novel fuel. XRD studies confirmed the formation of tetragonal structured WO3 successfully doped with Ag and W into its crystal lattice. Tauc plot confirmed the reduction in band gap of WO3 (2.77 eV) due to doping. SEM, TEM and EDX studies demonstrate the formation pure NPs with unique morphology having particle size in the range of ∼30–40 nm. Photodegradation studies revealed that 60 mg of NPs degraded MB dye completely in a short span of 30 min. The NPs showed good sensitivity towards electrocatalytic detection of NaNO2 with the LOD value of 21.23 μM. Further, the NPs proved to possess excellent photoluminescent and antioxidant activities. Doping improved its effective absorption of visible light that aid in the formation of electron hole pairs which in turn enhanced its multifunctional properties. The research manifests a simple, economical and eco-friendly synthetic method for synthesizing Ag-Mo-WO3 NPs on a large scale.
