High catalytic performance of Al–Pd–(Ru, Fe) icosahedral approximants for acetylene semi-hydrogenation

Three cubic crystalline icosahedral approximants (C phase: Al(72.0)Pd(16.4)Fe(11.6), P(40) phase: Al(72.0)Pd(16.4)Ru(11.6), P(20) phase: Al(70.0)Pd(22.3)Ru(7.7)) exhibit high ethylene selectivity of over 90% for hydrogenating acetylene at 150 °C. Moreover, the powdered P(20) also demonstrates a high...

description Three cubic crystalline icosahedral approximants (C phase: Al(72.0)Pd(16.4)Fe(11.6), P(40) phase: Al(72.0)Pd(16.4)Ru(11.6), P(20) phase: Al(70.0)Pd(22.3)Ru(7.7)) exhibit high ethylene selectivity of over 90% for hydrogenating acetylene at 150 °C. Moreover, the powdered P(20) also demonstrates a high catalytic performance under an industry-like ethylene feed containing 0.5% acetylene as an impurity. Overall, icosahedral approximants in the Al–Pd–(Ru, Fe) systems are promising as a novel class of alloy catalysts.
