Bimetallic Ru‐Fe Nanoparticles Supported on Carbon Nanotubes for Ammonia Decomposition and Synthesis

Abstract Alloy catalysts can achieve superior performance to single metal while reducing the cost by fine‐tuning the composition and morphology. Bimetallic Ru‐Fe nanoparticles were synthesized via liquid‐phase reduction method followed by impregnation with multiwall carbon nanotubes (CNTs) to prepare Ru‐Fe/CNTs catalysts. The Ru 3 Fe/CNTs catalyst yields a superior catalytic stability for ammonia decomposition compared to the Ru/CNTs catalyst. Hence, the ammonia synthesis rate of the Ru 3 Fe/CNTs catalyst was significantly higher than that of Ru/CNTs catalyst. The potential of bimetallic catalysts with reasonable composition and proportion will expand the research of efficient catalysts for ammonia decomposition and synthesis.
