Abstract

Electrochemical nitrogen fixation has received great attention in recent years due to its reliable and stable electrolytic efficiency. In this work, boron-doped carbon nitride with π-electron delocalization and vacancies was prepared by an in situ decomposition-thermal polymerization method. A series of characterizations were utilized to analyze the structure, morphology, and property. The results demonstrated that the secondary sintering and boron doping enhanced π-electron delocalization and induced the nitrogen vacancies of g-C3N4. The 0.24% boron-doped g-C3N4 electrocatalyst achieved the best ammonia yield (5.4 μg·h−1·mgcat−1) and the highest Faraday efficiency (14.1%) at −0.7 V vs reversible hydrogen electrode in 0.1 M Na2SO4. Furthermore, a feasible mechanism was proposed for the electrochemical nitrogen reduction process.
