| Abstract: | The physicochemical properties of MgAl hydrotalcite (HT) and the changes of property following increasing the calcination temperature were investigated in detail by using H2TPR, XRD, TGDTA and BET techniques. Transition metal oxides supported on MgOAl2O3 were synthesized by calcination of MgAlM(n (Mg) n (Al) n (M) =311; M=Cr, Mn, Fe, Co, Ni, Cu). The catalytic activity of the samples for NO reduction by CO was studied. The results showed that MgAlCu had far higher activity than other samples. The catalytic activity of the samples with different ratios of MgAlCu was measured and compared with that of CoMAl. |
