“…Yanovskaya et al introduced methoxyethanol as a useful solvent for electrochemical synthesis of metal alkoxides. In many cases this resulted in over 100% current efficiency which implies that simultaneous electrochemical dissolution and chemical oxidation took place.…”

“…This solvent can also be used for the synthesis of two- or three-element-containing compounds. For example, zirconium−yttrium compounds can be prepared by anodic polarization of yttrium in zirconium isopropoxide in methoxyethanol solution with a current yield of about 200%: Three mechanisms contribute to the dissolution process: (1) electrochemical dissolution; (2) chemical dissolution (by interaction of activated yttrium with methoxyethanol); (3) dissolution due to complex formation in the system Y(OR) 3 −Zr(OR) 4 −ROH further used Zr x Y y O n (OC 2 H 4 OCH 3 ) m for the preparation of ZrO 2 ·Y 2 O 3 of 0.2−0.5 μm thick films.…”

“…It was also concluded that the electrochemical synthesis of metal alkoxides can be used only for metals having standard potentials in the range 0.1-2 V (vs NHE). 329,330 Yanovskaya et al 334 introduced methoxyethanol as a useful solvent for electrochemical synthesis of metal alkoxides. In many cases this resulted in over 100% current efficiency which implies that simultaneous electrochemical dissolution and chemical oxidation took place.…”

This trend is apparent for example in electrochromic electrodes and ionic conductors, where amorphous materials provide better ionic mobility and in intercalated material applications such as V 2 O 5 -based sensors or RuO 2 -based suercapacitors where superior elasticity of the gels can accommodate volume changes with minimal stress.…”

The subject of sol-gel electrochemistry is introduced, starting with a brief account of milestones in its evolution. Then, the types of sol-gel materials that are useful for electrochemistry are presented, followed by a description of recent advances in the various fields of sol-gel electrochemistry. Modified electrodes, solid electrolytes, electrochromic devices, and corrosion protection coatings are described. Emerging fields such as RuO 2 supercapacitors and electrochemical synthesis of sol-gel precursors are also addressed.
