A new class of hollow mesoporous Pt–Ru and Pt particles with uniform size, named ‘mesoporous metallic cells’, are synthesized through a dual‐templating approach using colloidal silica particles and non‐ionic surfactants. To realize the full potential of mesoporous metals as electrocatalysts, the shell thicknesses, compositions, and hollow cavity sizes are precisely controlled.
