Electrodeposition and properties of nanostructured platinum films studied by quartz crystal impedance measurements at 10 MHz

Investigations of fuel cell reactions at the composite microelectrode|solid polymer electrolyte interface. I. Hydrogen oxidation at the nanostructured Pt|Nafion® membrane interface

“…The Pt film modified microelectrode was rinsed with copious acetone and water to remove surfactants. After this treatment the highly ordered nanostructure of the deposited film was checked using transmission and scanning microscopy [50,51]. Electrochemical characterization of the film using cyclic voltammetry and impedance spectroscopy confirmed the high surface area and concomitantly large double layer capacitances of these electrodes.…”

Electrochemical oxidation of hydrogen peroxide at nanoporous platinum electrodes and the application to glutamate microsensor

“…Corresponding research efforts have produced a number of impressive applications [2][3][4][5][6][7][8][9][10][11], one of which is applicability of nanoporous Pt for the enhancement of hydrogen peroxide (H 2 O 2 ) redox current [12]. Although accurate and reliable detection of H 2 O 2 is of interest in many fields, it has not been easy to detect H 2 O 2 accurately with amperometric techniques because its electrode reactions are complicated and voltammograms tend to be irreproducible at the majority of electrode surfaces [13,14].…”

Electrosynthesis and characterization of gold nanoparticles for electronic capacitance sensing of pollutants

“…In SAE processes, the control of NP morphology is realized by the use of a proper choice of electrochemical parameters and by the cathodic stabilization of the nanophases growing on the electrode surface [45]. In case of Pd-NPs, the electrolysis was proven to afford for a tight control over the core size and the experimental results were in good agreement with the fundamentals of electrocrystallization theory [42,46]. Recently, Huang et al [47] studied SAE processes carried out in the presence of a mixture of surfactants and demonstrated that the size of electrosynthesized Au-NPs can be controlled by the nature and relative amount of the surfactants, by the electrochemical parameters employed during the SAE preparation, and by the synthesis temperature.…”
