“…The resulting voltammograms during potential cycling were similar to those previously reported for electrodeposition of Pt on the carbon electrode in an aqueous Pt(IV) solution. [21][22][23] The new redox peaks observed during successive potential cycling in Figure 2(a) corresponded to H 2 evolution (1), H 2 adsorption (2), H 2 desorption (2'), oxide reduction (3), and oxide formation (3'), which were in good agreement with earlier reported values for a Pt wire electrode in PBS (pH 7.2).…”

A new synthesis route for Pt nanoparticles by direct electrochemical reduction of a solid-state Pt ion precursor (K 2 PtCl 6 ) is demonstrated. Solid K 2 PtCl 6 -supported polyethyleneimine (PEI) coatings on the surface of glassy carbon electrode were prepared by simple mixing of solid K 2 PtCl 6 into a 1.0% PEI solution. The potential cycling or a constant potential in a PBS (pH 7.4) medium were applied to reduce the solid K 2 PtCl 6 precursor. The reduction of Pt(IV) began at around −0.2 V and the reduction potential was ca. −0.4 V. A steady state current was achieved after 10 potential cycling scans, indicating that continuous formation of Pt nanoparticles by electrochemical reduction occurred for up to 10 cycles. After applying the reduction potential of −0.6 V for 300 s, Pt nanoparticles with diameters ranging from 0.02-0.5 µm were observed, with an even distribution over the entire glassy carbon electrode surface. Characteristics of the Pt nanoparticles, including their performance in electrochemical reduction of H 2 O 2 are examined. A distinct reduction peak observed at about −0.20 V was due to the electrocatalytic reduction of H 2 O 2 by Pt nanoparticles. From the calibration plot, the linear range for H 2 O 2 detection was 0.1-2.0 mM and the detection limit for H 2 O 2 was found to be 0.05 mM.

“…The concentration was much higher than that in other studies [7][8][9][12][13][14] because of the lower electrical resistance of the solution and a smaller change in the concentration of platinum ions during electrodeposition.…”

“…Owing to the high cost of bulk platinum materials, they are replaced with Pt thin films. Therefore, electrodeposition of the Pt thin films is so low in cost that many kinds of electrolytes [1][2][3], additives [4][5][6], substrates for platinum electrodeposition [7][8][9], and fabricating processes have been proposed.…”

Abstract:We have investigated the formation of a platinum thin film from a simple solution of dihydrogen hexachloroplatinate in a low temperature range of 283 to 295 K by a pulse current technique. Despite the low temperature, the platinum thin film observed with a confocal laser scanning microscope does not comprise particle aggregates but dense layer with a small surface roughness that tends to saturate at an initial growth stage. The deposition rate and current efficiency at a fixed average current density are evidently dependent on temperature. The analysis of the mol weight of platinum deposit based on two electrochemical reactions proposed in platinum electrodeposition elucidates the temperature dependence characterized by a thermal activation process.

“…The CV in the 5 th cycle exhibited two peaks: a reduction peak of Au 3+ and an oxidation peak of Au. The reduction peak potential of Au 3+ occurred at -0.48 V and the oxidation peak potential of Au at -0.09 V. The reduction peak current increased with an increase in the number of cycles due to the growth of the GNPs [44,45]. We deposited NiO onto the GNP-modified ITO electrode by performing a cathodic potential scan (-1.2 to 0.0 V) at an initial concentration of 10 mM Ni(NO 3 ) 2 .…”
