In this study, a novel silver-coblat ferrite (Ag-CoF) doped polyurethane (PU) nanofibrous mat has been synthesized by electrospinning technique without adding any foreign chemical for the in-situ reduction of Ag+ into metallic Ag nanoparticles (NPs). Synthesis of Ag NPs was achieved by the reduction ability of DMF, which played a dual role acting not only as a solvent but also as a reducing agent. Typically, a sol-gel consisting of CoF/PU and AgNO3 was stirred for 3h and electrospun. The crystalline structure and uniform distribution of Ag-CoF NPs in/on PU NFs was demonstrated by XRD and TEM, respectively. Two organic dyes, MB and RhB, were used to check the photocatalytic activity of the nanofibrous mat. Subsequently, photocatalytic investigation indicated that the prepared nanofibrous mat can be a potential candidate for the photodegradation of organic dyes under visible light irradiation. |
