Various carbon capture materials have been developed to mitigate CO2 emissions. However, adsorbent materials that are tolerant to the humid condition of real flue gases are rare. Here we report a N-doped porous carbon derived from polypyrrole a nitrogen-rich polymer, which can be used to capture...
For achieving high capture capacity and CO 2 /N 2 selectivity, precise control of porous structures and surface polarity is necessary. Herein we report the preparation of N-doped porous carbon via pyrolysis of microporous polyindole with KOH as the activator under N 2 . Analysis results suggest...

Herein, we made a highly reactive and stable isolated single-atom Fe/N-doped porous carbon (ISA Fe/CN) catalyst with Fe loading up to 2.16wt%. The catalyst showed excellent ORR performance with a half-wave potential ( E 1/2 ) of 0.900V, which outperformed commercial Pt/C and most non...
A newly designed N-doped porous carbon with magnetic nanoparticles formed in situ (RHC-mag-CN) was fabricated through simple impregnation then polymerization and calcination. The doped nitrogen in RHC-mag-CN was in the form of graphite-type layers with the composition of CN. The resultant nanocom...
In there, N,B-codoping of porous carbon has the greatest promotional effect in NRR. The electronic structure of these doped carbons determines the electrocatalytic activity. For instance, with the presence of B dopant, the fabricated N-doped materials exhibit a higher content of pyridinic-N. ...
