Abstract	Non-noblebimetallic CoW nanoparticles (NPs) partially embeddedin a carbon matrix (CoW@C) have been prepared by a facile hydrothermalcarbon-coating methodology followed by pyrolysis under an inert atmosphere.The bimetallic NPs, constituted by a multishell core–shellstructure with a metallic Co core, a W-enriched shell involving Co7W6 alloyed structures, and small WO3 patches partially covering the surface of these NPs, have been establishedas excellent catalysts for the selective hydrogenation of quinolinesto their corresponding 1,2,3,4-tetrahydroquinolines under mild conditionsof pressure and temperature. It has been found that this bimetalliccatalyst displays superior catalytic performance toward the formationof the target products than the monometallic Co@C, which can be attributedto the presence of the CoW alloyed structures.
