摘要：

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 BaY2O4 and it is suggested that Ba nano size particles play an important role for NO storage and the direct decomposition activity.
