Synthesis of Ozone in a Proton Exchange Membrane Electrochemical Reactor

Abstract
Deionized water was oxidized to ozone and oxygen at the anode in a proton exchange membrane electrochemical flow reactor. The optimum conditions for ozone generation were determined as a function of the applied voltage, electrode materials (lead dioxide powders obtained from two different commercial vendors), catalyst loadings, and reactant flow rates. Measured and calculated quantities included cell current, liquid‐ and gas‐phase ozone concentrations, and current efficiency.
