Carbon aerogels have attracted considerable attention over the past few decades as promising materials for catalyst supports, electrodes for supercapacitors and lithium-ion batteries, and adsorbents. However, expensive and toxic precursors as well as complicated synthetic methods dramatically limit their large-scale production and application. In this work, we developed a facile and effective route to prepare a N-doped carbon nanofiber aerogel (N-CNFA) with low mass density, continuous porosity, high specific surface area, and electrical conductivity from a bacterial cellulose precursor. Because of the highly porous and interconnected 3D structure, the obtained N-doped carbon aerogel was used directly as a catalyst for the oxygen reduction reaction (ORR), and it exhibited superior catalytic activity. This activity was much higher than that obtained without N-doping, and it can potentially be applied to high-performance fuel cells.
