In-situ Synthesis of Graphitic Carbon Nitride/Gold Nanoparticle Nanocomposites for Electrocatalytic Reduction of Iron(III)

摘要

The graphitic carbon nitride/gold nanoparticle (g-C3N4/AuNP) nanocomposites were reported in thispaper based on an in-situ synthetic method. After the protonation, ion-exchange, and chemicalreduction processes, the g-C3N4/AuNP nanocomposites were successfully obtained. The proposednanocomposites were investigated by various optical and electrical techniques, including scanningelectron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction spectroscopy(XRD), X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), etc. The g-C3N4/AuNPnanocomposites showed excellent electrochemical properties and their preliminary applications towardelectrocatalytic reduction of ferric iron were investigated. These nanocomposites exhibit promisingprospects for practical application in electrochemical analysis.
