AB  - The challenge in the electrosynthesis of fuels from CO2 is to achieve durable and 
      active performance with cost-effective catalysts. Here, we report that carbon 
      nanotubes (CNTs), doped with nitrogen to form resident electron-rich defects, can 
      act as highly efficient and, more importantly, stable catalysts for the 
      conversion of CO2 to CO. The unprecedented overpotential (-0.18 V) and 
      selectivity (80%) observed on nitrogen-doped CNTs (NCNTs) are attributed to their 
      unique features to facilitate the reaction, including (i) high electrical 
      conductivity, (ii) preferable catalytic sites (pyridinic N defects), and (iii) 
      low free energy for CO2 activation and high barrier for hydrogen evolution. 
      Indeed, DFT calculations show a low free energy barrier for the 
      potential-limiting step to form key intermediate COOH as well as strong binding 
      energy of adsorbed COOH and weak binding energy for the adsorbed CO. The highest 
      selective site toward CO production is pyridinic N, and the NCNT-based electrodes 
      exhibit no degradation over 10 h of continuous operation, suggesting the 
      structural stability of the electrode.
