“…With fossil fuels serving as the primary energy source for the foreseeable future, it is critical that the fuel efficiency of the vehicular fleet be increased at minimal cost to the economy. Diesel‐powered vehicles offer improved fuel efficiency compared to their spark‐ignited, gasoline‐powered counterparts (Clerc, 1996; Diesel Technology Forum, 2001; Farrauto and Voss, 1996; Frost and Smedler, 1995; Herzog, 1997; Lox et al, 1990). However, diesel engine exhaust has many adverse environmental effects because of the emission of nitrogen oxides (NOx), particulate matter (PM), and SO 2 .…”

“…An important number of catalytic formulations have been developed in this field, including oxides [11]- [14], perovskites [9] [15]- [17], spinels [18] and metals [19]. The range of metals refers to the use of noble metals [20] which are not favorable for commercial use due to their high cost.…”

The catalytic activity in the soot combustion is reported for a series of potassium-promoter alumina supported catalysts prepared by the sol-gel method to be used in the catalytic combustion of soot. The studied systems correspond to CeO 2-Al 2 O 3 and La 2 O 3-Al 2 O 3 with charges of 3 and 5 wt% of CeO 2 and La 2 O 3. Potassium impregnation is performed to reach 3 atoms of K per nm 2 of the mixed oxide. The effect of the potassium incorporation increases its reducibility, decreases the surface area and forms a new type of oxygen that is stronger than the oxygen in mixed oxides with similar chemical nature. The existence of potassium oxides, K 2 O and oxygen responsible for the vacancies and/or lattice defects (O 2−) are related to good catalytic activity. Additionally, the presence of alkali affects the structural and textural characteristics of the catalyst, promoting the catalytic activity in soot combustion.
