Abstract

Bimetallic nanoparticles of Pt and Sn have been prepared with an ion exchange of Sn2+ ions into KL zeolite containing 1-nm Pt nanoparticles. Incorporation of Sn does not cause a blockage for xenon adsorption. The results of data analysis of X-ray absorption fine structure show that the obtained particle size does not increase significantly. The microstructure of the PtSn nanoparticles seems to be Pt core covered with Sn. The obtained PtSn nanoparticles show a high selectivity to benzene with a comparable turnover rate for n-hexane aromatization.
