Due to the continuous increase in both industrial activities and in the use of internal combustion engines, the quality of atmospheric air has progressively deteriorated, both in urban conglomerates and globally [1]. These facts prompt restrictions in emission limits, making it necessary to increase research efforts in this area, and the development of increasingly sophisticated processes becomes evident. For several years, the use of catalytic processes to reduce pollutants in the atmosphere has become essential, including those from fixed and mobile sources. A typical example is a complex system currently used for the simultaneous reduction of CO, VOCs, NOx, and soot particles in the exhaust gases of diesel engines, for which a tandem of several catalytic reactors has been developed [2].
