I-ozone decomposition catalyst ekhiqizwa i-Xintan isetshenziselwa ukucekela phansi i-ozone ekukhishweni kwe-exhaust.Yenziwe nge-manganese dioxide(MnO2) kanye ne-copper oxide(CuO),ingabola i-ozone ibe umoya-mpilo ngendlela efanele ezingeni lokushisa elizungezile kanye nomswakama, ngaphandle kwanoma imaphi amandla engeziwe.
Ifaka ukusebenza kahle okuphezulu, ukusebenza okuzinzile kanye nempilo ende yokusebenza (iminyaka emi-2-3), isisusa sokubhujiswa kwe-Ozone sisetshenziswa kabanzi kumajeneretha e-ozone, amaphrinta okuhweba, ukuhlanzwa kwamanzi angcolile, ukubulala amagciwane kanye nokuvalwa inzalo okuhlobene nokusetshenziswa kwe-ozone.
