Abstract

original image

A metal-free electrocatalyst has been developed by doping carbon nanotubes with electron-deficient boron. The good performance in the oxygen reduction reaction originates from the enhanced O2 chemisorption and effective utilization of π electrons in the conjugated carbon from the boron doping, as revealed by DFT calculations.
