A COOH-terminated nitrogen-doped carbon aerogel exhibited 100% selectivity to two-electron oxygen reduction, exceeding reported carbonaceous and noble metal catalysts.
We report the design of a novel asymmetric supercapacitor (ASC) based on MnO/carbon aerogel (MnO/NCA) as the positive electrode and Fe2O3/carbon aerogel (Fe2O3/NCA) as the negative electrode.
A novel high-performance electrode material, nitrogen-doped carbon aerogel/cobalt oxide (NCA/Co3O4) material, was prepared by a facile, one step and in situ coating method, followed by a freeze-drying process.
