Abstract

Three cubic crystalline icosahedral approximants (C phase: Al72.0Pd16.4Fe11.6, P40 phase: Al72.0Pd16.4Ru11.6, P20 phase: Al70.0Pd22.3Ru7.7) exhibit high ethylene selectivity of over 90% for hydrogenating acetylene at 150 °C. Moreover, the powdered P20 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.
