Core/Shell Nanoparticles as Electrocatalysts for Fuel Cell Reactions

Nanoscale catalysis depends on 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.
