Abstract
Pt loaded La7.33BaYSi6O25.5 (Pt/La7.33BaYSi6O25.5) catalyst was investigated for oxidation of hydrocarbon species and for reduction of NO by hydrocarbon species. Pt/La7.33BaYSi6O25.5 catalyst exhibited higher activity for NO reduction by alkane (C3H8), alkene (C3H6) and aromatic (C7H8), than Pt/Al2O3 catalyst and Pt/CeO2–ZrO2 (CZ, CeO2/ZrO2 weight ratio was 1/1) catalyst. The oxidizing power for hydrocarbon species of carrier affected the catalytic activity for NO reduction. In addition, oxidation of adsorbed hydrocarbon on La7.33BaYSi6O25.5 was observed by FT-IR measurement. It was presumed that the catalytic activity for NO reduction is affected by adsorbed form of hydrocarbon.
