摘要

Derivatives based on metal frameworks (MOFs) are attracting more and more attention in various research fields. MOF-based derivatives x % MnO _( x ) –ZnO are easily synthesized by the thermal decomposition of Mn/MOF-5 precursors. Multiple technological characterizations have been conducted to ascertain the strengthening interaction between Mn species (Mn ~(2+) or Mn ~(3+) ) and Zn ~(2+) ( e.g. , XRD, FTIR, TG, XPS, SEM, H _(2) -TPR and Py-FTIR). The 5% MnO _( x ) –ZnO exhibits the highest NO conversion of 75.5% under C _(3) H _(6) -SCR. In situ FTIR and NO-TPD analysis showed that monodentate nitrates, bidentate nitrates, bridged bidentate nitrates, nitrosyl groups and C _( x ) H _( y ) O _( z ) species were formed on the surface, and further hydrocarbonates or carbonates were formed as intermediates, directly generating N _(2) , CO _(2) and H _(2) O.
