Fe- and Co-P4-embedded graphenes as electrocatalysts for the oxygen reduction reaction: theoretical insights.
TL;DR: Comprehensive density functional theory computations have revealed that the Fe- and Co-P4 moiety-embedded graphenes possess good stability and high chemical reactivity for O2 activation, thus facilitating the subsequent ORR steps, and a more efficient 4e pathway in both acidic and alkaline media is more energetically favorable.
