This paper reports the synthesis, characterization and application of a Ti-Bi2O3 anode for the electrochemical decolorization of the textile dye Reactive Red 2. The anode was synthesized by electrodeposition on a Ti substrate immersed in an acidic bismuth (III) solution at constant potential, followed by calcination in air at 600°C. Thermogravimetric Analysis (TGA), Energydispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) analysis revealed that the electrodeposited material was predominantly metallic bismuth, which was oxidized to pure α-Bi2O3 during the calcination in air. SEM micrographs revealed that the Bi2O3 coat at the anode surface was inhomogeneous and porous. Reactive Red 2 was completely electrochemically decolorized at the synthesized anode in the presence of H2O2. The applied current density, H2O2 and Na2SO4 concentration, medium pH and initial dye concentration affected the dye decolorization rate. The optimal process parameters were found to be as follows: an applied current density of 40 mA cm -2 using a mixture of 10 mmol dm -3 H2O2 and 10 mmol dm -3 Na2SO4 at pH 7. The dye decolorization rate was shown to decrease as its initial concentration increased. The decolorization reactions were found to follow pseudo-first order kinetics.

“…The electrochemical performances of Bi 2 MoO 6 nanoplates indicate the suitability of the material as a potential negative electrode material for supercapacitors. * Normally, this high-temperature polytype is unstable at room temperature, but can be stabilised by cation dopants [22] or due to nanoscale grain sizes [29].…”

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 .

“…Because the electrodeposition is characterized by the convenience of processing, low process temperature and low cost of raw materials and equipment, it is expected to find wide applications among the processes commonly used for the preparation of oxide ceramics. In recent years, nano-sized metal oxides prepared by cathodic electrodeposition have been an active research area, including preparation of zinc oxide [1,2], zirconium oxide [3], bismuth oxide [4], tungsten oxide [5], copper (I) oxide [6], titanium oxide [7], metal oxide composites [8], and even single-crystal oxide [9]. The nanocrystalline tin oxide has been synthesized successfully by cathodic electrodpeosition in our group [10].…”
