Synthesis and characterization of AgNi co-axial nanocables and their fluorescent and catalytic properties
Abstract: We report here a convenient, rapid one-pot synthesis of new metal–metal core–shell nanocomposites comprising silver nanowires (AgNWs) coated with nickel. The resulting AgNWs and nickel-coated silver nanocables average 60–80 nm in diameter were prepared by the polyol synthetic route. This method employed ethylene glycol as a reducing agent and polyvinylpyrrolidone as a capping agent. These nanomaterials are designated as AgNWs (0.1 M) and Ag@Ni (0.2 M), Ag@Ni (0.3 M), Ag@Ni (0.4 M), and Ag@Ni (0.5 M) nanocables based on the nickel content and were characterized by scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), UV–Visible (UV–Vis) spectroscopy, and photoluminescence (PL) spectroscopy. The morphology of each nanowire and nanocable was clarified using SEM, while EDX quantified the presence of Ni. XRD patterns confirmed the face-centered cubic structure of the nanomaterials. The Debye–Scherrer formula was applied to establish different characteristics such as crystallite size and lattice constant. Surface plasmon resonance was measured using UV−Vis spectroscopy and fluorescence of each product was determined by PL spectroscopy, respectively. Both the AgNWs and Ag@Ni nanocables catalyze the reduction of p-nitrophenol to p-aminophenol by sodium borohydride.
