Inhibiting Surface Diffusion to Synthesize 3D Bicontinuous Nanoporous N‐Doped Carbon for Boosting Oxygen Reduction Reaction in Flexible All‐Solid‐State Al‐Air Batteries (Adv. Funct. Mater. 38/2021)

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.
