摘要
Nanometer-scale catalysis depends oil spatial and surface arrangements of atoms. The synthesis of core/shell nanoparticles by synthetic approaches, the characterization of the core/shell nanostructures in terms of the relative core/shell compositions, and the demonstration of the electrocatalytic activities for fuel cell reactions (See figure), as reported in this Communication, have important implications to the design of desired nanoscale catalysts.
