Sol-Gel Materials in Electrochemistry

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 RuO₂ supercapacitors and electrochemical synthesis of sol-gel precursors are also addressed.
