Direct decomposition of NO into N2 and O2 on a C-type cubic (Gd1–xyYxBay)2O3–y solid solution catalyst is investigated. These novel catalysts are found to exhibit higher activity and conversion rates than conventional La-containing perovskite oxide catalysts for NO decomposition. C-type cubic (Gd1–xyYx-Bay)2O3–y catalysts are therefore considered to be possible candidates for the conversion of harmful exhaust gases.
