“…[11][12][13] A series of essential catalysts for ozone decomposition have been developed, of which the most active and productive candidates for catalytically converting ozone to oxygen molecules are indeed noble metals and transition metal oxides. 12,14 Transition metal oxide-based catalysts are incredibly efficient from an environmental perspective and simultaneously provide a convenient and affordable way to decompose the ozone molecules. In this regard, transition metal oxides including MnO 2 , [15][16][17] Cu 2 O/CuO, 10,18 Fe 2 O 3 , 19,20 and NiO 21 have been reported as active catalysts.…”
