Electrochemical ozone production using diamond anodes and a solid polymer electrolyte

Electrolysis of water by use of a simple solid polymer electrolyte sandwich with diamond anode, Nafion® polymer electrolyte and diamond cathode leads to efficient ozone production. The dependence of ozone production rate on current density, water flow rate and water conductivity have been investigated. Ozone production is favoured by high flow rate and low conductivity of the electrolysed water.
