Description
Summary:[Display omitted] •Synthesis of polymer stabilized silver nanoparticle in a single step under ambient condition.•In-situ synthesised silver nanoparticles show catalytic activity for proton-coupled electron transfer reaction.•Polymer stabilized silver nanoparticles also show catalytic activity for the electrochemical recognition of ascorbic acid. A facile in situ synthesis route [1] has been described for the preparation of polymer stabilized silver nanoparticles. Such in situ synthesized silver nanoparticles are shown to have excellent catalytic activity for the reduction of 4-nitrophenolate (4NP), an example of a proton-coupled electron transfer (PCET) reaction mechanism. Also, the silver-polymer nanocomposite material is shown to perform as an efficient electro-catalyst for the oxidation of ascorbic acid.
