In article number 1907690, Zhigang Geng, Jie Zeng, and co‐workers report a fluorine‐doped 3D porous carbon framework as a highly efficient metal‐free catalyst toward N2 electroreduction. F‐bonding to carbon atoms creates a Lewis acid site to enhance the repulsive interaction with protons for suppressing H2 evolution, thus enhancing the selectivity of N2 electroreduction into NH3.
N2 electroreduction into NH3 represents an attractive prospect for N2 utilization. Nevertheless, this process suffers from low Faraday efficiency (FE) and yield rate for NH3. In this work, a highly efficient metal‐free catalyst is developed by introducing F atoms into a 3D porous carbon framework (F‐doped carbon) toward N2 electroreduction. At −0.2 V versus reversible hydrogen electrode (RHE), the...
