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.
