Catalysis-tunable Heusler alloys in selective hydrogenation of alkynes: A new potential for old materials.

ABSTRACT: Heusler alloys (X ₂ YZ) are well-established intermetallic compound materials in various fields because their function can be precisely adjusted by elemental substitution (e.g., X ₂ YZ _1-x Z' _x ). Although intermetallic compound catalysts started attracting attention recently, catalysis researchers are not familiar with Heusler alloys. We report their potential as novel catalysts focusing on the selective hydrogenation of alkynes. We found that Co₂MnGe and Co₂FeGe alloys have great alkene selectivity. Mutual substitution of Mn and Fe (Co₂Mn _x Fe_1-x Ge) enhanced the reaction rate without changing selectivity. The substitution of Ga
