Abstract

NO decomposition was investigated over Cu ion-exchanged aluminophosphate molecular sieve catalysts. Cu ions in cationic positions balanced by one framework negative charge in the metalloaluminophosphates of AlPO-5 and AlPO-11 structures exhibited catalytic activity in NO decomposition comparable with that of Cu-ZSM-5. No catalytic activity of the Cu ions incorporated during synthesis of molecular sieves into the framework in tetrahedral positions (CuAlPO-11) was observed. The catalytic activity of Cu-MeAlPO-5 and Cu-MeAlPO-11 was observed with various divalent metal ions of the MeAlPO-5 and MeAlPO-11 frameworks (Me = Zn, Mg, Fe, Co) and also with Cu exchanged SAPO-5 molecular sieves. The Cu-MeAlPO-5 and Cu-MeAlPO-11 catalysts differed only in the temperature of the maximum observed catalytic activity.
