祝贺骆诗剑同学文章《MOF-derived C@NiO@Ni electrocatalyst for N2 conversion to NH3 in alkaline 

electrolytes 》被英国皇家化学学会(RSC )旗下的期刊Sustainable Energy &Fuels(IF:4.912)接受。



Today, industrial ammonia synthesis mainly depends on the Haber-Bosch process which causes a lot of 

energy consumption and huge CO2 emissions.Electrochemical N2 reduction reaction (NRR) is considered as

 a more sustainable and environmentally benign alternative to produce ammonia, but requires efficient 

catalyst to overcome the difficulty of N2 activation. In this work, we report that MOF-derived C@NiO@Ni 

microtubes behave as a high-efficiency electrocatalyst in 0.1 M KOH electrolyte. This electrocatalyst 

achieves a high NH3 yield of 43.15 μg h-1 mg-1cat. and a Faradaic efficiency of 10.9% at -0.7 V vs. 

reversible hydrogen electrode. Experimental results indicate the excellent NRR performance originates from

 the oxygen vacancies in NiO. Moreover, abundant NiO/Ni interfaces are conductive to proton adsorption 

and further enhance the NRR performance
