Novel Ir-substituted hexaaluminate catalysts were developed for the first time and used for catalytic decomposition of high concentration of N 2 O. The catalysts were prepared by one-pot precipitation and characterized by X-ray diffraction (XRD), N 2 -adsorption, scanning electronic microscopy (SEM) and temperature-programmed reduction (H 2 -TPR). The XRD results showed that...
In this study, a novel bifunctional catalyst IrFe/Al 2 O 3 , which is very active and selective for preferential oxidation of CO under H 2 -rich atmosphere, has been developed. When the molar ratio of Fe/Ir was 5/1, the IrFe/Al 2 O 3 catalyst performed best, with CO conversion of 68% and oxygen selectivity towards CO 2 formation of 86.8% attained at...
