Electropolymerized supermolecule derived N, P co-doped carbon nanofiber networks as a highly efficient metal-free electrocatalyst for the hydrogen evolution reaction

In this work, for the first time, we report the synthesis of N, P co-doped carbon derived from electrochemically polymerized supermolecules. The as-obtained N, P co-doped carbon fiber networks show ultra-efficient HER activity as a metal-free electrocatalyst with an overpotential of 151 mV to reach a current density of 10 mA cm(-2).
