- Abstract
Starting from the requirement of an ecological way to reduce emissions in the exhaust gases of thermal power plants, the current paper analyzes the manner of obtaining specific catalysts for oxidizing CO and HC using different support materials (carbon molecular sieve, alumina, zeolite) and high catalytic activity metals (Cu, Co, Mg, Pd, Ni, Zr, Ti) and characterizes these from a physicalstructural point of view. The characterization of the prepared catalysts was done by X-ray diffraction, optical microscopy, electronic transmission microscopy, atomic adsorption, textural studies with mercury porosimetry. It was noticed that the presence of palladium considerably improves the reduction degree of copper and cobalt oxides, increases the degree of dispersion and decreases the metal crystal size in the support mass, besides its role as an active catalytic component. These improvements lead to an increase in the catalysts' activity, aspect which will be considered in the next step of the research.
