Abstract: A series of MP-like catalysts LaAAl11O19 and LaAMnAl10O19 (A stands of Cd,Zn,Zr) were prepared by co-precipitation method. The structure and the properties of these catalysts were investigated by using BET,XRD techniques and activities of methane catalytic combustion. The influence of different transition metal on the morphological and catalytic activity of the catalysts was studied. The results show that the catalyst with good crystal is obtained after calcination at 1 200 ℃. And all catalysts have the high catalytic activity and stability. The introduction of different transition metal has much effect on the properties of catalysts. The synergism is observed between the different metal ion. Catalytic activity is enhanced by synergism. LaZnMnAl10O19  has the higher catalytic activity in methane combustion and its light-off T 10% is 472 ℃, total conversion  T 90% is 734 ℃.
