A novel nanomaterial/ionophore-modified glassy carbon electrode for anodic stripping analysis of lead (Pb2+) is described. Nanosized hydroxyapatite (NHAP) with width 20−25 nm and length 50−100 has been prepared used to improve the sensitivity detection Pb2+ because it provides unique three-dimensional network structure strong adsorption ability toward Pb2+. An ionophore, usually in ion-selective electrodes, utilized here its excellent selectivity Nafion, a cation-exchange polymer, employed...
We have proposed a Fenton-like reaction-mediated etching of gold nanorods and applied it to the sensitive visual detection Co(2+) ions. With presence bicarbonate (HCO3(-)) hydrogen peroxide(H2O2), ions trigger reaction, resulting in generation superoxide radical (O2(•-)). As result, are gradually etched by O2(•-) SCN(-), accompanied an obvious color change from green red. The process preferentially occurs along longitudinal direction, which is observed transmission electron microscope....
Developing new materials and novel technologies for the highly efficient treatment of toxic organic pollutants is desirable. Chemical reduction based on heterogeneous substrate/noble metal catalysts reducing agent NaBH4 has become an effective method in recent years. Here, a spherical covalent framework (SCOF) was designed to provide basic sites Ag ions, by which small NPs were immobilized SCOF form NPs@SCOF microspheres. The prepared microspheres exhibited high catalytic ability toward...
A new catalyst support, polyoxometalate-modified carbon nanotubes, is presented in this paper through the chemisorption between polyoxometalate and carbon. Pt Pt−Ru nanoparticles were electrochemically deposited on nanotubes electrodes, their electrocatalytic properties for methanol electro-oxidation are investigated detail. Due to unique electrical of excellent redox high protonic conductivity polyoxometalate, similar deposition charge catalysts, 1.4 times larger exchange current density,...
A simple colorimetric method with high sensitivity and selectivity was developed for sensing of nitrite as low 4.0 μM by naked eyes, which is based on etching gold nanorods accompanied shape changes in aspect ratios (length/width) a visible color change from bluish green to red then colorless the increase nitrite.
A new type of all-solid-state polymeric membrane ion-selective electrodes (ISEs) is developed by using a nanoporous gold (NPG) film as solid contact. The NPG in situ formed on the surface wire electrode multicyclic electrochemical alloying/dealloying method. characteristics film, such large area, high double layer capacitance, and good conductivity, have been demonstrated cyclic voltammetry impedance spectroscopy. offers well-defined interface between electronic conductor membrane....
Copper (Cu) is an essential trace element for plankton, but excessive amounts can be toxic and threaten the ecosystems human health. However, determination of low concentration labile Cu (CuLabile) in complex water environments remains a huge challenge. In this work, gold microelectrode (μ-GE) with high sensitivity anti-fouling capability was fabricated based on double-layer membrane framework consisting ion-exchange polymer (Nafion) agarose gel (LGL). The Nafion stabilized surface μ-GE not...

Based on inducing the aggregation of gold nanoparticles (AuNPs), a simple colorimetric method with high sensitivity and selectivity was developed for sensing thiocyanate (SCN−) in aqueous solutions. Citrate-capped AuNPs were prepared following classic Tween 20 subsequently added as stabilizer. With addition SCN−, citrate ions surfaces replaced due to affinity between SCN− Au. As result, molecules adsorbed separated aggregated. The process accompanied by visible color change from red blue...
Gold nanoparticles (Au NPs) supported on graphene oxide (GO) have been proven as a high-performance catalyst for fast reduction of organic contaminants due to their strong electrostatic interactions enhance the electron transfer ability from an donor acceptor. However, GO sheets in solution often suffer reaggregated problems π–π interaction, greatly affecting catalytic efficiency. Herein, we solved this drawback through supporting tiny GO@Au NPs nanocomposites micrometer-sized porous...
