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...
