Optimization of the dispersion of gold and platinum nanoparticles on indium tin oxide for the electrocatalytic oxidation of cysteine and arsenite

Autor: James A. Cox, Laisheng Sun, Diep Vu Ca

Publikováno v: Electrochimica Acta. 51:2188-2194

Gold and platinum nanoparticles (NPs) were prepared by chemical reduction of the corresponding metal complex bound by ion-exchange to generation-4 poly(amidoamine) dendrimers (PAMAM). Arrays of the NPs on indium tin oxide (ITO) electrodes were formed

Electrocatalysis of the hydrogen evolution reaction by nanocomposites of poly(amidoamine)-encapsulated platinum nanoparticles and phosphotungstic acid

Autor: Diep Vu Ca, Laisheng Sun, James A. Cox

Publikováno v: Journal of Solid State Electrochemistry. 9:816-822

Poly(amidoamine) dendrimer (Generation-4) encapsulated platinum nanoparticles (PtNP-PAMAM) were prepared and used to fabricate nanocomposites with Keggin-type phosphotungstic acid (PW12O403−) using a layer by layer electrostatic assembly technique.

The influence of the matrix structure on the oxidation of aniline in a silica sol–gel composite

Autor: Justyna Widera, Richard T. Taylor, Gilbert E. Pacey, H. Perfect, Diep Vu Ca, Anna M. Kijak, James A. Cox

Publikováno v: Electrochimica Acta. 50:1703-1709

Mesoporous and microporous silica matrices were formed on indium tin oxide electrodes for liquid-phase voltammetry and as monoliths for solid-state voltammetry of aniline. The pore structure, which was verified by scanning probe microscopy and by sur
