“…This observation seems to be related with the higher dispersion of metal particles on KCu2/Al 2 O 3 . It is also related, with the fact that metal oxides can catalyse the oxidation of soot [19][20][21][22]. Finally, as it was above commented, the support acidity seems to explain the difference in the C 3 H 6 conversion [12].…”

“…For an example, the T i and T p of Co-based catalysts decrease to 269°C and 350°C from 316°C and 430°C respectively, due to the promoting effect of potassium. The promoting effect on soot oxidation is contributed to the increase of surface mobility by loading potassium, improving the contact between solid catalyst and solid soot [24].…”

“…It was found that Ba-containing systems show good performances both in removal of particulate matter and NO x . Potassium is another element that has shown potential as a NO x storage component; besides, in several papers [5][6][7][8][9][10] it has been reported that potassium shows distinct activity in the soot oxidation. Accordingly, in this work the potentiality of a K-based catalyst in the simultaneous removal of particulate matter and NO x was investigated.…”
