ELECTROCHEMISTRY AND GREEN CHEMICAL PROCESSES: ELECTROCHEMICAL OZONE PRODUCTION

Recebido em 25/11/02; aceito em 1/4/03 After an introductory discussion emphasising the importance of electrochemistry for the so-called Green Chemical Processes, the article presents a short discussion of the classical ozone generation technologies. Next a revision of the electrochemical ozone production technology focusing on such aspects as: fundamentals, latest advances, advantages and limitations of this technology is presented. Recent results about fundamentals of electrochemical ozone production obtained in our laboratory, using different electrode materials (e.g. boron doped diamond electrodes, lead dioxide and DSA-based electrodes) also are presented. Different chemical processes of interest to the solution of environmental problems involving ozone are discussed
