Carbonaceous particles emitted into the atmosphere come from different combustion processes in industries, power plants and means of transport. Soot particles are carriers of harmful organic compounds, and can cause various diseases [1]. Diesel engines are considered one of the main sources of soot, being important not only the mass emitted, but also the size of the particles, since the smaller the size, the greater the penetration into the lungs. Until now, diesel particulate filters have been the most effective way to remove these particles, as they have the capacity to retain them by filtration and then burn them in situ with the action of a catalyst duly incorporated into the filter, taking advantage of the high temperatures generated in the exhaust pipes. In this framework, the elaboration of particulate filters from flexible materials such as ceramic papers was proposed, with the addition of active phases, Co,Ce or Co,Ba,K, for the combustion of different types of diesel soot.
