Mixed oxide catalysts for pollution control

Mixed oxide catalysts for pollution control

The following mixed oxide catalysts have been investigated for auto exhaust control: LaRhO 3, SrRuO 3, SrY 0.5Ru 0.5O 2.75, LaNi 0.5Ru 0.5O 3 and NiOCr 2O 3 spinel. For auto exhausts, LaRhO 3 had equivalent oxidation activity as platinum; SrRuO 3 and SrY 0.5Ru 0.5O 2.75 were superior for NO reductio...

Zusammenfassung:The following mixed oxide catalysts have been investigated for auto exhaust control: LaRhO 3, SrRuO 3, SrY 0.5Ru 0.5O 2.75, LaNi 0.5Ru 0.5O 3 and NiOCr 2O 3 spinel. For auto exhausts, LaRhO 3 had equivalent oxidation activity as platinum; SrRuO 3 and SrY 0.5Ru 0.5O 2.75 were superior for NO reduction and low NH 3 formation.
