Research Progress on Carbon-based Materials in Electrocatalytic Ammonia Synthesis
Ammonia,as an important fertilizer and energy carrier,faces challenges due to the high energy consumption and carbon dioxide emissions associated with traditional synthesis methods like the Haber-Bosch process.This has prompted a search for more environmentally friendly and energy-efficient alternatives.Electrochemical nitrogen reduction reactions(ENRR)have emerged as a promising alternative.However,ENRR still encounters challenges,including competition from hydrogen evolution reactions(HER)and the nitrogen reduction reaction(NRR),affecting catalyst activity,yield,and Faradaic efficiency(FE).Recent research has focused on enhancing the activity and selectivity of electrocatalysts.This paper combines electrocatalytic mechanisms to review the current state of carbon-based materials in NRR,providing crucial guidance and insights toward more efficient and sustainable methods for ammonia synthesis.These advancements hold promise for future ENRR studies and the development of environmentally friendly ammonia production.
