Abstract

N2O was decomposed over Rh supported on NaY zeolite and ZSM5. With low Rh-loading (≤0.1 wt.%) the activity of Rh was much higher than that supported on SiO2 and CeO2. On the contrary, the activity of Rh-loaded zeolites (0.1 wt.%) was not so high or even lower than that on SiO2 for the oxidation of toluene, which has a larger molecular size than N2O. Thus the Rh present inside the zeolite cavity was especially effective in the decomposition of N2O.
