Platinum cluster catalysts supportedon porous chelate resin-metal complexes: Effect of resin porosity on catalytic activity
- Univ. of Tokoyo, Hongo, Bunkyo-ku (Japan); and others
Porous chelate resin-metal complexes were prepared from a commercial chelate resin having iminodiacetic acid moieties. This was accomplished by complexing with multivalent cations such as Al{sup 3+} and drying after washing with ethanol. The supported platinum cluster catalysts, formed by reducing the platinum ions on the porous chelate resin-metal complexes, had a mean diameter of 26 {Angstrom}, occupying pores approximately 40 {Angstrom} in diameter of the chelate resin-metal complexes. These systems were then used as catalysts during the hydrogenation of olefin or diene. The catalytic activity was found to depend on the type of metal ion used in the chelate resin-metal complexes, and it increased in the order of Na{sup +} < Mg{sup 2+} < Al{sup 3+}. The surface area of the chelate resin-metal complex, measured by a BET method, also increased in the same order, suggesting that the surface area is related to the catalytic activity. 23 refs., 6 figs., 3 tabs.
