ABSTRACT:
An electrolyte contains a tetravalent salt of titanium and a trivalent salt of cerium in a methanesulfonic acid solution. A reducing agent consisting of trivalent titanium and an oxidizing agent consisting of tetravalent cerium are provided in the same solution. An electrochemical cell is disclosed wherein the catholyte and anolyte utilize this electrolyte. The reduction of tetravalent titanium into trivalent titanium is accomplished by electrolysis in the presence of extraneous trivalent cerium ions. The oxidation of trivalent cerium into tetravalent cerium is accomplished by electrolysis in the presence of extraneous tetravalent titanium ions. Simultaneous reduction of tetravalent titanium into trivalent titanium and oxidation of trivalent cerium to tetravalent cerium by electrolysis is also disclosed. Reduction of organic compounds using trivalent titanium in the presence of trivalent cerium in methanesulfonic acid is disclosed. Oxidation of organic compounds using tetravalent cerium in the presence of tetravalent titanium is disclosed.
