摘要：

Cu ions were incorporated into MgAlPO-11 and ZnAlPO-11 molecular sieves by ion exchange procedure from the Cu acetate solution. The number of the Cu ions in MeAlPO-11 corresponded roughly to the number of the negative charges in the framework produced by the substitution of trivalent aluminium by divalent Mg or Zn cations. Both Cu-MeAlPOs exhibited constant conversion in NO decomposition in time-on-stream (T-O-S). The turn-over-frequency (T-O-F) values of NO per Cu atom of Cu-MeAlPO-11 at 770 K are comparable to those of the Cu ions implanted in the cationic sites of high silica ZSM-5 matrix.
