WebAug 1, 2024 · Ozone (O 3), as a harmful air pollutant, has been of wide concern.Safe, efficient, and economical O 3 removal methods urgently need to be developed. Catalytic decomposition is the most promising method for O 3 removal, especially at room temperature or even subzero temperatures. Great efforts have been made to develop … WebFeb 28, 2024 · At the heating temperature of 393 K, the decomposition rate of ozone ( Cdec) exhibits a peak at the first stepwise increase in the ozone concentration to 40 g m −3 with a rise time on the order of seconds and a magnitude of approximately 0.18. However, Cdec rapidly decreases to 0.05 then to almost zero.
