PdPt bimetallic cluster supported on KL zeolite probed with xenon adsorption measurement, EXAFS/XANES and n-butane hydrogenolysis
Pt catalyst in KL zeolite is converted to PtPd bimetallic catalyst by the ion exchange Pd(NH3)(4)(2+) and subsequent reduction in hydrogen flow at 573 K. The results of xenon adsorption measurement, hydrogen chemisorption, Xe-129 NMR spectroscopy and X-ray absorption fine structure spectroscopy indicates the formation of PdPt bimetallic cluster inside the KL zeolite channel. It is believed that n-butane hydrogenolysis occurs over the obtained PdPt bimetallic cluster in the absence of multiple pore blockage.
