Abstract

Direct decomposition and storage of nitric oxide (NO) on Ba-Y mixed oxide with four different catalysts, Ba₃Y₄O₉, BaY₂O₄, BaO/Y₂O₃ and Ba _0.5/BaY₂O₄ were investigated. Among the examined phases, it was found that Ba_0.5/BaY₂O₄ which is obtained by decomposition of Ba₃Y₄O₉ in helium at 1123 K shows relatively high NO decomposition activity at high temperature and a large capacity for NO storage at low temperature. XRD measurement suggests the formation of nano sized barium particles on BaY ₂O₄ and it is suggested that Ba nano size particles play an important role for NO storage and the direct decomposition activity.
