1Theoretical study on the application of the largest aluminum-pyrazole ring in electrochemical nitrogen reduction reaction显示文摘Electrochemical nitrogen reduction reaction(NRR)is a mild and sustainable method for ammonia synthesis.Therefore,developing high activity,selectivity,and economic efficiency catalysts with considering the synergistic effects between catalysts and carriers to design novel structural models is very important.Considering the non-noble metal NRR catalyst,Mo3,we tried to find a suitable carrier which is stable and economical.Herein,we used the largest atomically precise aluminum-pyrazole ring(AlOC-69)to date(diameter up to 2.3 nm).The larger ring cavities and the presence of abundant hydroxy groups make AlOC-69 an ideal molecular carrier model and provide a basis for studying its structure-activity relationship.The formation energy(-0.76eV)and stable Mo-0 bonds indicate that Mo_(3)can be stabilized on the Al_(10)O_(10)surface.Additionally,N_(2)has fully activated due to the strong interaction between the p-orbital of N and the d-orbital of Mo.The low limiting potential(-0.28V)emerges that Mo_(3)@Al_(10)O_(10)has ideal catalytic activity and selectivity.This research provides a promising catalyst model and an understanding of its catalytic process at the atomic level,providing a new approach for the co-design of catalyst and carrierin NRR.Zirui Wang Sihao Shen Yupeng Han Weihui Fang Qiaohong Li Jian Zhang 2023Chinese Chemical Letters2023,34,12:0
