AB  - Carbon nanotubes (CNTs) possess remarkable mechanical, electrical, thermal, and 
      optical properties that predestine them for numerous potential applications. The 
      conventional chemical vapor deposition (CVD) route for the production of CNTs, 
      however, suffers from costly and complex issues. Herein, we demonstrate a general 
      and high-yield strategy to grow nitrogen-doped CNTs (NCNTs) on three-dimensional 
      (3D) graphite felt (GF) substrates, through a direct thermal pyrolysis process 
      simply using a common tube furnace, instead of the costly and complex CVD method. 
      Specifically, the NCNTs-decorated GF (NCNT-GF) electrode possesses enhanced 
      electrocatalytic performance towards cerium redox reactions, mainly due to the 
      catalytic effect of N atoms doped into NCNTs, and ingenious and hierarchical 3D 
      architecture of the NCNT-GF. As a result, the cell with the NCNT-GF serving as a 
      positive electrode shows the improved energy efficiency with increases of about 
      53.4% and 43.8% over the pristine GF and the acidly treated GF at a high 
      charge/discharge rate of 30 mA cm(-2), respectively. Moreover, the as-prepared 
      NCNT catalyst-enhanced electrode is found to be highly robust and should enable a 
      long-term cycle without detectable efficiency loss after 500 cycles. The viable 
      synthetic strategy reported in this study will contribute to the further 
      development of more active heteroatom-doped CNTs for redox flow batteries.
