Abstract

Abstract Fe-containing HMCM-68 was prepared by a direct hydrothermal method (Fe-HMCM-68) or by impregnation of HMCM-68 with different iron precursors (Fe 2 O 3 /HMCM-68, FeCl 3 /HMCM-68). Their structure and acid properties were characterized by XRD, N 2 adsorption, UV–Vis and NH 3 -TPD. The benzylation of toluene by benzyl chloride showed that these Fe-containing HMCM-68 zeolites were highly active catalysts for this reaction and could be reused. The activity of the Fe-containing HMCM-68 is controlled mainly by their redox properties and the effect of zeolitic acidity has been further discussed.
