Abstract
A novel synthetic approach had been worked out for block catalysts of compositions 0.1%Pd-2.9%CuO/g-Al2O3 and 0.1%Pd-2.9%CuCo2O4/g-Al2O3. Their catalytic properties had been investigated in neutralization reactions of toxic components of exhaust gases, i.e. CO oxidation, deep oxidation of hydrocarbons and NOx reduction by propane. It has been demonstrated that, due to higher specific surface area and dispersion of active components synthesized by burning method, the activity of these catalysts is significantly higher as compared to the samples yielded by a standard methods.
