Pyridinic Nitrogen

A novel bioinspired polydopamine derivative was prepared by self-polymerization of 6-(2-aminoethyl)-3-hydroxypyridin-2(1H)-one in an alkaline medium. It could be used as precursor to produce pyridinic N-rich carbon nanocapsules with a desired N doping content and superior electrocatalytic activity and stability for the ORR.
