Zeolitic imidazolate frameworks derived nitrogen doped porous carbon for electrochemical reduction of CO2

Abstract

The development of high-performance electrochemical materials plays an important role in CO2 reduction efficiency and cost effectiveness. In this work, nitrogen doped porous carbon matrix was designed and fabricated from zeolitic imidazolate frameworks (ZIF-8). Pyrolysis temperature was investigated to achieve the best performance to convert CO2 into CO. The suitable temperature is 700 °C which could make the catalyst containing good conductivity and activity. The highest Faradaic efficiency of CO is close to 25% at potential of -1.0 V.
