Nanoporous Carbon In article number 2103632 Kailong Hu, Hua‐jun Qiu, Yoshikazu Ito, and co‐workers report a polyaniline‐assisted template method to synthesize 3D bicontinuous nanoporous N‐doped carbon particles. Importantly, the polyaniline efficiently inhibits the surface diffusion‐caused template coarsening and pore enlargement, achieving a pore size of 35 nm and a high N‐dopant concentration up to 7.20 at.%. Benefiting from the bicontinuous nano‐sized pore channels and rich doping sites, these materials show potential applications as electrode catalysts for portable and flexible devices.
