中文摘要	in this contribution, we present an efficient, versatile and green strategy for finely controlling the metal (oxide) coating on core particles through in situ reaction of precursors in co(2) expanded ethanol without using any precipitants. it not only avoids the formation of free metal (oxide) and/or naked cores, but also permits individual dispersion of all the resultant particles without aggregation. with this method, the composition, thickness, uniformity, and structure of the metal (oxide) shell could be precisely controlled. a wide variety of unreported high-quality core-shell particles with a shell consisting of highly dispersed metal (oxide) nanocrystals or nanoalloys, such as c@ni, coo/c, c@ni&co and c@ni&pd particles have been fabricated, and the properties of the resultant particles were precisely tailored, such as the promising catalytic performance obtained over ni/c and c@ni particles in the hydrogenation of nitrobenzene. the present coating strategy is more simple and precisely controllable compared to the conventional deposition method and it is suitable for most precursors and even for multi-component materials, enabling the fabrication of nanostructured materials more easily and precisely.
