Carbon nanotube-encapsulated cobalt for oxygen reduction: integration of space confinement and N-doping

We report carbon nanotube-encapsulated cobalt as an efficient oxygen reduction electrocatalyst (onset potential of 0.94 V and half-potential of 0.84 V). Calculation results firstly reveal that Co protected by graphitic-N-doped carbon holds more negative charge (−1.22 eV) and has an energy barrier (0...
