Mg-Al hydrotalcites were intercalated with deca- and bivanadate that was proved by FT-IR and XRD measurements. Thermal decomposition of these precursors resulted in formation of effective catalysts for selective catalytic reduction (SCR) of NO with NHs. The catalytic performance of vanadium catalysts was compared with Cu-containing mixed metal oxides obtained from hydrotalcite precursors. The calcined Cu-Mg-Al hydrotalcites have been found to be active in low-temperature region while the V-catalysts prevailed in high temperature SCR.
