1. A method of performing a redox reaction in an undivided electrochemical cell comprising the steps of:
- disposing a first electrode in a liquid electrolyte solution, said first electrode being at least 80% efficient for the oxidation or reduction of inorganic or organic redox couples in said liquid electrolyte solution;
simultaneously disposing a second electrode in said electrolyte solution as a counterelectrode to said first electrode, said second electrode being formed of substiochiometric titanium oxide of the formula TiOx, where x is in the range 1.67 to 1.9; and
applying a potential across said electrodes so as to oxidize or reduce the desired component of said redox couples.
