Abstract
Specifics of electrochemical synthesis of titanium dioxide in water-containing electrolytes based on ethylene glycol with conductive additives of ammonium fluoride were investigated at potentials of 1 – 14 V using method of anodic polarization. The process of electrochemical oxidation of ammonium cation in ethylene glycol based electrolyte was investigated. Results of kinetic electrochemical oxidation of ammonium cation are presented. Hypothesis about the role of ammonium ion in the process of electrochemical synthesis of porous titanium dioxide at potentials of 1 – 14 V is suggested.
Keywords: titanium dioxide; anodic polarizations; ammonium fluoride; water-containing organic electrolytes.
