Structural functional design of catalysts for conversion of nitrogen(I, II) oxides

The results of structural functional design of catalysts for the reduction of nitrogen(I) and nitrogen(II) oxides and the simultaneous conversion of NO and N2O are reviewed. Catalysts based on metals of the platinum group on structured supports for the reduction of nitrogen oxides (NOx) by carbon monoxide and methane and three-component transformations (CO/NO/CnHm) are presented together with complex oxide catalysts (Cu,Cr,Fe/gamma-Al2O3) for the selective reduction of NOx with ammonia. Bifunctional metal-oxide (Co, Cr, Ce, In, Fe) catalysts and those doped with Rh (Pt) and deposited on ZrO2,Al2O3, and H-ZSM-5 and their binary composites for the reduction of NO and N(2)ObyC(1)-and C-3-C-4 hydrocarbons are examined.
