抜粋

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.
