Abstract
MCM41s incorporated with bimetallic copper and titanium were first synthesized by hydrolyzed the mixed solutions of sodium metasilicate (Na2SiO3), cuprammonia (Cu(NH3)4(NO3)2) and cetyltrimethylammonium bromide (CTAB) with diluted sulphuric acid containing titanium sulfate (Ti(SO4)2). The samples were characterized by using XRD, FT-IR, N2 adsorption isotherms, UHRTEM, TG-DTA and ICP techniques. It was revealed an ordered hexagonal structure, a narrow pore distribution, high surface area and relatively high thermal stability of the prepared materials. Some structure parameters of the samples varied linearly with the total heteroatoms content. All the characterization results indicated that the atoms of Cu and Ti might be incorporated into the framework of MCM41.
