1D/2D Interface Engineering of CoPc-C3N4 heterostructure for boosting nitrogen reduction reaction to NH3

Exfoliated C 3 N 4 sheets were employed to wrap the CoPc nanotubes (NTs) to synthesize the electrocatalyst; the CoPc–C 3 N 4 system showed excellent nitrogen reduction to ammonia with a yield rate of 423.8 μg h −1 mg cat −1 and a FE of 33% at −0.2 V vs. RHE.
