| 英文摘要 | the nature and location of copper in cu/ssz-13 zeolites synthesized by using a one-pot hydrothermal approach with cu-tetraethylenepentamine as a template and by the ion exchange of ssz-13 were investigated by applying h-2-temperature- programmed reduction, ftir, epr, and in situ raman spectroscopic techniques. the one-pot synthesized cu/ssz-13 zeolite contains predominantly isolated copper ions in the large cages, whereas copper species in the ion-exchanged cu/ssz-13 zeolite occupy sites in the large cages of the chabazite (cha) structure and the six-membered rings of the cha structure. if the one-pot synthesized cu/ssz-13 zeolite is exchanged with the nh4no3 solution in addition to the removal of a part of copper ions, the remaining copper ions in the cha structure relocated from the large cages to the six-membered rings. isolated copper dominated in all cu/ssz-13 zeolites. the in situ raman spectra demonstrated that cu-o-cu dimers form at higher copper content. the bis-mu-oxo dicopper(iii) complex is observed only in the ion-exchanged sample upon dehydration. the higher no selective catalytic reduction activity of the one-pot synthesized sample in a wide temperature range appears to be due to the predominance of isolated cu2+ sites in the large cages, and their higher reactivity is possibly owing to the lower stability of cu2+ at these sites. |
