Nitrogen-enriched polydopamine analogue-derived defect-rich porous carbon as a bifunctional metal-free electrocatalyst for highly efficient overall water splitting

Abstract

A carbon-based, bifunctional metal-free water splitting electrocatalyst is prepared using a nitrogen-enriched polydopamine analogue to produce defect-rich porous carbon, which exhibits superb catalytic activities for both the HER and the OER.
