英文摘要	nitrogen-incorporated sapo-11 molecular sieves were synthesized by a secondary synthesis technique at low nitridation temperature (400degreesc) with a starting material of sapo-11 zeolite doped with 2 wt % ru. the obtained powder samples showed high activity in knoevenagel condensation, which acts as a probing reaction for base catalysis. the changes in structure of the nitrogen-incorporated samples were investigated by means of (27)al-mas nmr and (31)p-mas nmr spectra, x-ray diffraction, and bet surface area measurements. it was found that nitrogen-containing species had incorporated into the framework of sapo-11 zeolite, in which some n atoms directly bonded to al and p atoms and formed aln(4), aln(2)o(2), and pn(4) groups. these species with terminal-nh(2) groups on the surface together were responsible for the basicity of nitrogen-incorporated sapo-11 zeolite.
