Abstract
Surface enhanced Raman scattering (SERS), photocatalytic and antibacterial activities of Fe3O4/Ag magnetic nano particle (MNP) is reported in this work. A synthesized Fe3O4/Ag MNP is characterized with UV–visible, vibrational spectral studies (FT-IR), X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and transmission electron microscopy (TEM). VSM reports Fe3O4/Ag MNP posses good magnetic response and attribute as a SERS substrate. SERS property of Fe3O4/Ag MNP has studied with 10–8 M, 10–10 M and 10–12 M concentrations of R6G. Photocatalytic efficiency was calculated with both R6G and environmentally ignored real (leachate) sample. The degradation takes place with rate constant ˷ 0.012 min−1. Moreover, degradation efficiency of Ag NPs has improved with Fe3O4 NPs. Also, as synthesized substrate shows an antibacterial activity against gram negative and gram positive bacteria with an inhibition zone of 5–8 mm. Both photonic and antibacterial properties make this material as promise for potential applications in environmental pollution, human medicine and contaminated drinking water.
