Ozone decomposition – state of the art and new approaches

The effective ozone decomposition is still a scientific challenge because of its rising industrial use in global scale. Wide application of high ozone concentrations forces researchers to work on new catalytic systems for ozone removal concerning mostly the surrounding human environment (airplane cabins, copiers, laser printers, sterilizers, etc.). It is not an easy task considering the fact that above concentration of 0.1 mg/m3 the ozone could seriously harm human health. Current studies estimate a huge number of untimely deceased people per year on a global scale as a direct consequence of air pollution. It is imposing to reinforce the efforts in workable ozone decomposition on ground atmospheric layer as an important part of air purification process. This review comprises general look on basic physico-chemical properties of ozone completed by recently reported literature about catalytic ozone destruction. Discussion over kinetics and mechanisms of ozone decomposition reaction will be represented in order to do an attempt to clarify these most outstanding parts of the topic.
