Quantitative evaluation of O-2 activation half-reaction for Fe-N-C in oxidase-like activity enhancement

摘要

The oxidase-like activity of high-performance Fe-N-C was enhanced by up to 55% by using a secondary N-containing precursor in pyrolysis. Moreover, the exploration of the O-2 activation half-reaction using electrochemical methods was disclosed to be a practically facile approach to quantitatively evaluate the factors associated with the activity.
