Mo-X4 (X= O, NH and S) Mediated Triphenylene-Based Two-Dimensional Carbon-Rich Conjugate Frameworks for Efficient Nitrogen Reduction Reaction

The electrocatalytic nitrogen reduction reaction (NRR) activities of two-dimensional carbon-rich conjugate frameworks (2D-CCFs) can be regulated by changing the atoms X (X = O, NH and S) in the Mo-X 4 motifs.
