摘要: Abstract Pt catalyst in KL zeolite is converted to PtPd bimetallic by the ion exchange Pd(NH 3 ) 4 2+ and subsequent reduction hydrogen flow at 573 K. The results of xenon adsorption measurement, chemisorption, 129 Xe NMR spectroscopy X-ray absorption fine structure indicates formation PdPt cluster inside channel. It believed that n- butane hydrogenolysis occurs over obtained absence multiple pore blockage.
