## Description

- description: Metallic foil catalysts allow easier control of composition and microstructure
    than conventional supported metal catalysts. They are promising catalytic materials
    for investigating the relationship between microstructures and catalytic properties
    by controlling the introduction of lattice defects. It was reported that twin
    boundary defects formed in Au–Al alloy catalysts might be the origin of catalytically
    active sites. In this study, we focused on Ti–Pd–Ni alloy foils that undergo martensitic
    transformation and can form twin boundary defects. The relationship between the
    twin boundary structure and the acetylene hydrogenation properties of Ti–Pd–Ni
    alloy foils was investigated. The catalytic performance for the acetylene hydrogenation
    was evaluated using Ti–Pd–Ni alloys (Ti50Pd50, Ti50Pd30Ni20, Ti50Pd20Ni30, Ti50Ni50
    (at.%)), which exhibit martensitic transformation temperatures ranging from room
    temperature to above 500℃. The acetylene conversion rates displayed mountain-shaped
    curves during both heating and cooling processes for all samples. A decrease in
    conversion rate was observed during the cooling process compared to the heating
    process, likely due to a reduction in surface Pd contents caused by the formation
    of titanium oxides. A high selectivity toward ethylene (>60%) was observed for
    all samples. However, we did not find clear correlation between catalytic activities
    and phase changes associated with martensitic transformations, probably because
    of the influence of titanium oxide formation which changed surface composition
    and microstructure in Ti–Pd–Ni alloys.
