Abstract:
Heusler alloys are the ternary or multicomponent intermetallic compounds characterized by specified crystal structures, tunable electronic configurations, and diverse physical properties. The intermetallic Heusler alloys have emerged as promising candidates for chemical and electrochemical catalysis in recent years. Herein, this review provides a comprehensive overview of recent development of intermetallic Heusler alloys as catalytic materials, with a focus on their preparation methods and catalytic applications in hydrogenation and dehydrogenation conversion, water splitting, field-assisted catalysis, etc. The research on Heusler alloy catalysts is in the preliminary exploration stage while is experiencing rapid development. This review also outlines the future prospects of these novel materials and their potential applications.

Heterogeneous Catalysis
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
The hydrogenation process takes place on the surface of...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
