Pt nanoparticles covered with a film of microporous carbon (Pt@C) were uniformly embedded in mesoporous carbon (MC; see schematic) by in situ deposition of Pt and glucose polymerization in the pores of mesoporous silica (SBA‐15), which was subsequently removed by etching. The nanometer‐scale hybrid material shows superior catalytic performance for methanol‐tolerant oxygen electroreduction.
