Abstract

(Figure Presented) Multifunctional catalysts: Nickel-gold alloy nanoparticles (NPs) are synthesized in solution, by means of a fast butyllithium reduction method, and then used to prepare NiO-stabilized Au NP catalysts through a phase-transformation process (see scheme). The silica-supported catalysts exhibit a remarkable resistance to sintering and are highly active for CO oxidation.
