Abstract

Of cores! Core–shell Au@metal-organic-framework-5 (MOF-5) nanoparticles (NPs), in which a single Au NP core is coated with a uniform MOF-5 shell, were prepared by a facile one-pot method. The diameter of the Au NP core and the thickness of the MOF-5 shell are easily tuned by controlling the reaction conditions. These nanoparticles are selective sensors of CO2 in gas mixtures.
