摘要：

C-shell catalysts: Uniform hollow nanoshells of graphitic carbon have been synthesized by phase separation of Ni3C nanoparticles (NPs) followed by chemical leaching of the nickel core gave graphite-shell particles (see picture). Pt□NPs anchored onto the shell show high apparent activity for the oxygen reduction reaction. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
