3/1/2019 · The simultaneous co- electro deposition of nano-Pt and nano-MnOx onto the GC electrode with several molar ratios from 1:0 to 1:8 is carried out in 0.1 M Na 2 SO 4 containing 2.0 mM H 2 [PtCl 6] and 2.0 mM Mn(CH 3 COO) 2 solution at ? 0.2 V for 5 min. Effort is actually expanded before assigning this deposition potential in order to ensure the simultaneous deposition of both ingredients (nano-Pt.
In this paper, a new methodology replacing the typical sequential layer-by-layer immobilization, i.e.
simultaneous co-electrodeposition protocol is proven eminent for assembling efficient binary nanoelectrocatalysts for formic acid (FA) electro-oxidation (FAO). This strategy is successful to integrate homogeneously Pt nanoparticles (nano-Pt essential component for FA adsorption/oxidation) with.
We presented a novel Au–Ag bimetallic nanodendrite constructed through simple one-step co-electrodeposition on a Pt surface in the presence of iodide ions as a co-reagent. Simultaneously, we maneuvered to generate hydrogen bubbles from the same surface by the reduction of proton to drive the growth of deposition into the nanodendrite network structure.
A PtAuBi-UPD composite electrocatalyst modified glassy carbon electrode (GCE) is prepared via the simultaneous underpotential deposition (UDP) of Bi and bulk deposition of Pt and Au, followed by stripping of the accessible Bi, and it shows high performance for.
7/28/2006 · It is shown that the correct polarization curves for Ni and Co powders and Ni–Co alloy powders electrodeposition could be obtained only after IR drop correction, since the total current density of electrodeposition at the most negative potential of ?1.4 V versus Ag|AgCl is extremely high (up to about 3–6 A cm ?2) as a consequence of simultaneous hydrogen evolution which starts immediately.
Abstract. A facile co-electrodeposition method has been developed to fabricate reduced graphene oxide/polypyrrole (rGO/PPy) composite films, with sodium dodecyl benzene sulfonate as both a surfactant and supporting electrolyte in the precursor solution.
In this paper, we report on our efforts to evaluate NiSn as anode electrocatalysts for simultaneous hydrogen evolution and lignin depolymerization in a biomass-depolarized electrolyzer. Different ratios of NiSn alloys were synthesized through co-electrodeposition of Ni and Sn from a.
The transfer coefficients (? 1 and ? 2), exchange current density (i 0), and Tafel slopes can be used to explain the simultaneous electrodeposition of two metals (say Me 1 and Me 2). Assuming Me 1 is the metal having always more positive reduction potential (noble metal) compared to the metal Me 2 reduction potential ( Kanani, 2006 ).
5/24/2020 · Huan TN, Kim S, Tuong PV, Chung H (2014) Au–ag bimetallic nanodendrite synthesized via simultaneous co-electrodeposition and its application as a SERS substrate. RSC Adv 4:3929–3933 CAS Article Google Scholar, 11/17/2014 · Ennaoui et al. first reported a co-electrodeposition scheme for Cu 2 ZnSnSe 4 alloy that was post-annealed using under H 2 S environment at 550 °C for 2 h and the resulting solar cell showed an efficiency of 3.4% . Addition of selenium to the system results in a band gap-lowering that helps to get a higher current density.
