Abstract
In electrolytic cells for producing ozone, the ozone current efficiencies can be enhanced by providing electrodes, and especially anodes, fabricated from glassy carbon. Cells including such glassy carbon electrodes are capable of producing ozone at very high current efficiencies utilizing aqueous electrolytes of highly electronegative fluoro-anions.
Claims2
A method for producing ozone at high current efficiencies from an electrolytic cell comprising passing an electric current at high oxygen overvoltages through a bare glassy carbon anode and a cathode into an electrolyte comprising a strongly acidic aqueous solution of highly electronegative BF.sub.4.sup.- fluoro-anions.
