Steam reforming of methanol (CH3OH+H2O→3H2+CO2) has been performed on a stable AlCuFe quasicrystal. The AlCuFe quasicrystal reveals excellent activity after leaching treatment. The production rate of H2 reaches 235 l/kg·min at 553 K. The quasicrystals have two advantages: one is their brittle nature, which allows them to be crushed efficiently; the other is thermal stability as a catalyst support, which make their high temperature application possible. Catalysts prepared from Al-Cu-Fe alloys with various compositions were also evaluated. Al63Cu25Fe12 was shown to have the highest activity per unit area among Al-Cu-Fe alloys.
