Theoretical study of the nitrogen reduction reaction catalyzed by a B-doped MoO 2 six-membered ring
In this study, two potential catalysts with double-B atom-doped atomic MoO (B /MoO ) and single-B atom-doped atomic MoO (B/MoO ) were designed and constructed. The thermodynamics and selectivity of two catalysts in the nitrogen fixation reaction were analyzed by a DFT calculation method. The results...

Summary: | In this study, two potential catalysts with double-B atom-doped atomic MoO
(B
/MoO
) and single-B atom-doped atomic MoO
(B/MoO
) were designed and constructed. The thermodynamics and selectivity of two catalysts in the nitrogen fixation reaction were analyzed by a DFT calculation method. The results show that B
/MoO
shows better adsorption activation and reduction and can effectively activate nitrogen molecules by two adjacent boron atoms. It achieves an extremely low overpotential of -0.18 V and rapid NRR kinetics through an enzymatic mechanism. Therefore, B
/MoO
is a very promising NRR candidate catalyst. This research shows that doping with diatomic B (as an active site) results in an excellent NRR catalytic activity, which provides a certain theoretical basis for the preparation of high-performance NRR catalysts. |
