Title: Synthesis of Si-Al/MCM-41 and ion exchange of Pt(NH_3)_4~(2+) inside mesoporous channel
Abstract: Mesoporous molecular sieve Si-Al/MCM-41 was synthesized by hydrothermal method with a gel molar composition of SiO 2∶0.1Al 2O 3∶0.5Na 2O∶CTABr:mesitylene:156H 2O. After calculation, Pt cluster has keen supported on the MCM-41 following a procedure of ion exchange of Pt(NH 3) 2+ 4. The MCM-41 materials have been comprehensively characterized by N 2 adsorption/desorption at 77 K.The chemical shift in 129 Xe NMR spectroscopy of adsorbed xenon indicates that the Pt cluster is located inside the mesoporous molecular sieve MCM-41.
