| Abstract |
The consecutive ion-exchange of Co and Pd on zeolites, followed by calcination, originates the formation of different metal species making these catalysts active for the CH(4)-SCR of NO. According to UV-Vis spectroscopy and H(2) temperature programmed reduction results, it is possible to verify that the introduction of Pd on Co-HFER catalyst induces a redefinition of the cobalt oxides species, promoting the formation cobalt-oxo cations. These modifications appear to have a direct effect in improving the catalysts performance, providing an increase of 30 \% in the NO(x) conversion to N(2), in the presence of oxygen excess. |
