Summary: In this work, the potential active V-N center was obtained through theoretical prediction and successfully constructed on N-doped carbon materials. The catalyst exhibited excellent electrocatalytic performance for nitrogen reduction reaction with high faradaic efficiency and NH3 yield rate. Structural characterization and density functional theory calculations confirmed the high performance of the catalyst originated from the tuned d-band upon coordination with nitrogen, in line with the original design intention. Such a rational design-controllable synthesis-theoretical verification strategy may be effective for other chemical processes as well.

Summary: The electrocatalytic reduction of nitrate to ammonia offers a new way to generate ammonia from waste water, but the competition between nitrate conversion and hydrogen evolution reaction (HER) limits its development. This study synthesized MoS2 with sulfur vacancies (SVs) and used these SVs to promote the production of ammonia. MoS2 with SVs showed higher ammonia synthesis performance and faradaic efficiency. The research enhances our understanding of how to handle the content of MoS2 with SVs when preparing monolayered MoS2 with special catalytic properties.
