Nickel Hydroxide-Cobalt Hydroxide Nanoparticle Supported Ruthenium-Nickel-Cobalt Islands as an Efficient Nanocatalyst for the Hydrogenation Reaction

摘要

The RuNiCo tri-metallic nanocatalyst of Ru islands-on-nickel-cobalt/nickel hydroxide-cobalt hydroxide nanoparticles (Ru/NiCo/Ni(OH)(2)-Co(OH)(2)/C) was prepared at room temperature (RT) via hydrazine hydrate reduction and galvanic replacement methods. And Ru/NiCo/Ni(OH)(2)-Co(OH)(2)/C exhibited much higher catalytic activity in the model reaction of toluene hydrogenation than Ru/Ni/Ni(OH)(2)/C and Ru/Co/Co(OH)(2)/C due to synergistic effect of Ru, Ni and Co related species, with good stability.
