چکیده

The Present Bio-synthesis is an efficient, fast, cheap, nontoxic, simple and eco-friendly protocol for silver nanoparticles synthesis, which is more beneficial than commonly used physiochemical methods. Here in silver nanoparticles are biosynthesized using Citrus sinensis var. Kozan yerly fruit juice as reducing and stabilizing agent. The X-ray diffraction (XRD) pattern confirms the crystalline nature of silver nanoparticles. The high resolution transmission electron microscopy confirmed that the silver nanoparticles ere of average 4-10 nm particle size. The UV–vis absorption spectrum shows a characteristic surface plasmon resonance absorption peak of silver nanoparticles at 443 nm. FTIR confirmed phytochemicals of Citrus sinenses var kazan yerly fruit juice involved in the synthesis and stabilization of silver nanoparticles. Furthermore, the silver nanoparticles modified electrode (Ag/GC) exhibited an excellent electro-catalytic activity toward the red-ox reaction of phenolic compounds (Catechol) and DPPH free radical scavenging activity. The synthesized silver nanoparticles are stable and comparable in size. These silver nanoparticles showed potential applications in the fields of electrochemistry, sensors, catalysis, nanodevices and medical.
