Abstract

Titanium oxide on MCM-41 was synthesized using the atomic layer deposition (ALD) method. BET, XRD, NH3-TPD and EDS were used to study the structural properties of the supported titanium oxides. The surface area of catalysts decreased with increasing of the amount of titanium in precursor solution. However, unique characteristics of 2-D hexagonal structure of mesopores in MCM-41 were maintained. The Ti/MCM-41 catalyst with titanium loading of 12.6 wt% showed the highest activity in the dehydration of 2-butanol, which was attributed to the highest overall amount of acid sites among the Ti/MCM-41 catalysts.
