Dispersible, highly graphitic, and nitrogen‐doped carbon hollow nanospheres (25–90 nm), termed ‘nanobubbles’, are prepared via confined carbonization through a silica nanocasting technique. Poly(ionic liquid) nanoparticles are employed as easy‐to‐make and multifunctional templates, which simultaneously act as both the carbon and nitrogen source. The promising potential of the nanobubbles in oxygen reduction reactions for fuel cells is demonstrated.
