Abstract

NO direct decomposition on Y₂O₃ based oxide was studied and it was found that doping Ba and Ni simultaneously in Y₂O₃ is effective for achieving the high NO decomposition activity. The optimized amount for Ni and Ba doping is 5 and 0.5–1 mol%, respectively and on this Y₂O₃ based catalyst showed almost 100% N₂ yield at 800 °C and high N₂ yield was sustained under co-existence of oxygen. Effects of tensile strain caused by Au dispersion was further studied for increasing low temperature NO decomposition activity and it was found that NO decomposition activity around 500 °C was much increased by dispersion of 1 mol% Au which induced a tensile strain.
