• Synthesis of silver nanoparticles-decorated FePO4 nanosphere at a gas-liquid interface for the electrochemical detection of Hydrogen peroxide

Silver nanoparticles were prepared by chemical reduction of acetaldehyde gas in the absence ofprotective gas, and Ag/Fe$PO_{4}$ nanocomposites were synthesised by modified silver mirror reaction at a gasliquidinterface. A hydrogen peroxide $(H_{2}O_{2})$ electrochemical sensor was constructed through immobilizing Ag/Fe$PO_{4}$ nanocomposites on gold (Au) electrode. The morphology and composition of the nanocompositeswere characterized by transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy(EDS). The electrochemical investigations of the sensor indicated that it exhibited excellent analytical performancewith a wide linear range from $3.0 \times 10^{-5}$and $1.1 \times 10^{-2}mol$L^{-1}$a low detection limit of 4.7μmol.$L^{-1} at a signal-to-noise ratio of 3. Meanwhile, it also showed acceptable reproducibility and anti-interference ability.This study may provide a new method for the synthesis of highly dispersed metal nanoparticles which mightbe used in other related fields.
