Synthesis of Co2FeGe Heusler alloy nanoparticles and catalysis for selective hydrogenation of propyne

Abstract

Although intermetallic compounds are attracting attention of catalysis researchers, ternary intermetallic catalysts have scarcely been investigated due the difficulty of synthesizing supported nanoparticles. In this study, we successfully synthesized SiO₂ supported Co₂FeGe Heuslar alloy nanoparticles. This catalyst exhibited high catalytic performance for selective hydrogenation of propyne by nano-sizing.
