摘要: Abstract Various ZSM-5 zeolites with iron contents ranging from of 0.86 to 4.98 and Si/Al ratios 11.5–140 were prepared by solid-state ion exchange FeCl 2 . The catalysts characterised XRD, H -TPR NH 3 -TPD. formation stability surface oxygen over these investigated a transient multipulse technique combined subsequent temperature-programmed desorption (TPD). Higher enhance the oxygen. However, when critical content is reached, larger oxide clusters particles are formed do not contribute significantly formation. Moreover, amount desorbed more than that N O due additional present in lattice such clusters. TPD studies indicate presence different species depends on both zeolite ratio.
