“…First, the goldyellow shining film of Bi 2 O 3 was deposited onto the surface of the BiBE in pure phosphate buffer solution (pH 6.0) by cycling the potential between À 1.5 and 1.0 V. During the anodic scan, two oxidation peaks and a plateau were observed indicating the transformation of metal Bi(0) into Bi(III), the formation of bismuth oxi-species and the passivation of the bismuth oxide layer, respectively (not shown). This behavior was found to be in full agreement with that described in works where the thin bismuth oxide film was studied from the viewpoint of its applicability in super-or semi-conductors [27,32,34,39]. We then examined the electrochemical behavior of the so prepared Bi 2 O 3 -modified BiBE in the presence of potassium hexacyanoferrate(III) or Ru(NH 3 ) 6 Cl 3 ( Figure 4A and B).…”

A bismuth bulk electrode (BiBE), a new solid-state electrode, is presented. The polycrystalline metal bismuth diskshaped electrode was examined for its anodic stripping voltammetry performance, which was found to be well comparable to that achieved with the bismuth or mercury film electrodes. Useful potential windows of the BiBE in aqueous solutions of pH 1 to 13 were found to range from approximately À 1.7 to À 0.1 V, depending on pH, where either hydrogen evolution or anodic dissolution of metallic bismuth limit the electrochemical inertness of the BiBE. Employing cyclic voltammetry (CV), the cathodic behavior of the BiBE was examined by testing inorganic (cadmium(II) ions) and organic (2-nitrophenol) model compounds; a CV quasi-reversible behavior was recorded in the case of the Cd(II)-Cd(0) couple. The characteristics of the BiBE under anodic conditions, i.e., at bismuth surface coated with a thin conductive Bi 2 O 3 film, was examined by testing two well-established redox systems, potassium hexacyanoferate(III) and ruthenium(III) hexaaminechloride; a nearly reversible behavior was recorded in the latter case. Based on the presented preliminary results, BiBE can be considered as an interesting alternative to common solid and (toxic) mercury electrodes for possible use in electrochemical studies and electroanalytical applications.

“…The observed high peak current in 1 M NaNO 3 and 1 M NaOH electrolyte is due to the partial dissolution of the oxide into BiO 2 − ionic species and the reversible reaction of Bi(III) to Bi metal [38,39]. that the anionic size is played an important role to achieve the high specific capacitance of the electrode.…”

“…The observed redox reactions is attributed to the reversible reaction of bismuth(III) to Bi metal, which indicates pseudocapacitance [38,39]. The redox reactions in bismuth molybdates is similar to bismuth oxide and redox properties of bismuth oxide in hydroxide group containing electrolyte (KOH, NaOH) was well described in various works [38][39][40][41]. The reports pointed out that the reduction of bismuth oxide is due to the partial dissolution of the oxide to BiO 2 − ionic species in hydroxide group containing electrolyte.…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. is analyzed by cyclic voltammetry and galvanostatic charge-discharge techniques. The effect of Na based aqueous electrolytes on capacitance of the Aurvillius type structured Bi 2 MoO 6 is investigated. As prepared γ-Bi 2 MoO 6 nanoplates provide the high specific capacitance (519 Fg -1 ) compared with the high-temperature monoclinic phase γ(H) Bi 2 MoO 6 in 1 M NaOH electrolyte. The obtained high specific capacitance of as prepared Bi 2 MoO 6 could be attributed to the decrease in particle size, increase in active sites, and nano plate-like structure of as prepared γ-Bi 2 MoO 6 .

Electrochemical properties for mixed gold-bismuth electrodes have been evaluated. Increased overpotential towards the hydrogen evolution reaction (HER) was found as a function of increased bismuth content in the gold-bismuth mixture. Compared to a bare gold electrode, the overvoltage was increased by 80 mV for gold with 2% bismuth added (AuBi2), 170 mV for 6% bismuth added (AuBi6), and 580 mV for 25% bismuth added (AuBi25). Cyclic voltammetry (CV) in a NaOH solution was also carried out to study the formation of different oxide products on the surface. The practical use of such electrodes was demonstrated by differential pulse anodic stripping voltammetry (DPASV) for the detection of copper and mercury, and good linearity was found even for concentrations down to 0.25 mg/L. In addition to stability tests in NH 4 Cl, the analytical use and stability over time were evaluated in purified scrubbing water and polluted river water.
