Ozone (O3),as a harmful air pollutant,has been of wide concern.Safe,efficient,and economical O3 removal methods urgently need to be developed.Catalytic decomposition is the most promising method for O3 removal,especially at room temperature or even subzero temperatures.Great efforts have been made to develop high-efficiency catalysts for O3 decomposition that can operate at low temperatures,high space velocity and high humidity.First,this review describes the general reaction mechanism of O3 decomposition on noble metal and transition metal oxide catalysts.Then,progress on the O3 decomposition performance of various catalysts in the past 30 years is summarized in detail.The main focus is the O3 decomposition performance of manganese oxides,which are divided into supported manganese oxides and non-supported manganese oxides.Methods to improve the activity,stability,and humidity resistance of manganese oxide catalysts for O3 decomposition are also summarized.The deactivation mechanisms of manganese oxides under dry and humid conditions are discussed.The O3 decomposition performance of monolithic catalysts is also summarized from the perspective of industrial applications.Finally,the future development directions and prospects of O3 catalytic decomposition technology are put forward.
