Heptazine vs Triazine: Phase-Dependent Activity of V-Doped C3N4 Catalysts in Electrochemical N2 Reduction.
Electrochemical nitrogen reduction reaction (ENRR) offers a sustainable pathway for ambient ammonia synthesis, yet its practical implementation is hindered by low efficiency and selectivity. Herein, we report a phase-engineered strategy for tailoring the structure of vanadium-doped graphitic carbon nitride (V@C3N4) cat...
