Abstract
AbstractThe grafting reaction of SnMe4 on the surface of Pt/NaY zeolite was investigated in a 1.6 × 104 Pa hydrogen atmosphere. The chemical compositions, structure and properties of the resulting solid were characterized by in situ FTIR, ICP, XRD, XPS, temperature programmed decomposition and nitrogen adsorption. The results show that Pt atoms of Pt/NaY zeolite react with tetramethyltin to form a bimetallic Me3SnPt surface species in the presence of hydrogen at 353 K. The reaction does not destroy the zeolite framework, while its surface properties are changed. The BET surface area and the pore volume of the zeolite decrease significantly. The CO chemisorption results and the XPS results show that the electronic properties of the modified Pt atoms on the surface of NaY zeolite are altered remarkably by the inductive effect of electron between Pt and methyl groups. The grafted product has excellent selective hydrogenation of furfural to furfuryl alcohol. Copyright © 2007 John Wiley & Sons, Ltd.
