The Electrochemical Behavior of Titanium Improved by

The electrochemical growth of titanium oxide nanotubes on titanium and its alloys has a history of about 14 years [70]. Zwilling et al. [32] first produced nanotubular titanium dioxide on titanium, and the fabrication of titanium oxide nanotube arrays via anodic oxidation of titanium foil in a fluoride-based solution were first reported in 2001 by Grimes and co-workers [59].

Electrochemical Supercapacitors as Versatile Energy

Chemical and mechanical stability in supercapacitors can be improved by mixing noble metal oxides with valve metal oxides, such as titanium oxide and tantalum oxide (). On the other hand, mixing two or more oxides always results in some deterioration of the high-frequency capacitance since valve metal oxides do not contribute to the electrochemical proton exchange.

Electrochemical Descaling of Metal Oxides from

After the electrochemical experiments, an ICP–MS instrument (NexION 300 ICP–MS, PerkinElmer, Inc., Waltham, USA) was used to analyze the components of the metal and metal oxides dissolved in the solutions. In ICP–MS analysis, the main constituents of

Corrosion

Galvanic corrosion occurs when two different metals have physical or electrical contact with each other and are immersed in a common electrolyte, or when the same metal is exposed to electrolyte with different concentrations.In a galvanic couple, the more active metal (the anode) corrodes at an accelerated rate and the more noble metal (the cathode) corrodes at a slower rate.

Chemical and electrochemical behavior of titanium, silicon,

2012/10/17The process of dissolution of titanium, silicon, and boron oxides in carbonate melts is studied. Voltammetric studies are used to show that the most electropositive electrochemical process in molten carbonates is discharge of carbon dioxide dissolved in the melt to elementary carbon. Electrochemical synthesis of carbides in carbonate melts is possible at the potentials more positive by

Nickel/Cobalt/Tin ternary composite: Composition

2 Electrochemical techniques including cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy were used to estimate the electrochemical performance of composites. The voltammograms revealed that the mixture with a greater amount of nickel favored the specific capacity, obtaining a maximum exclusively by faradaic reactions on electrode surface.
