Plasma catalysis has recently been recognized as a promising route for artificial N reduction under mild conditions. Here we report a highly active VN catalyst for plasma-catalytic NH synthesis the typical Mars-van Krevelen (MvK) mechanism. Our results indicate that NH synthesis occurs through the continuous regeneration and elimination of nitrogen vacancies on the VN surface. With this strategy, the VN catalyst achieves a superhigh NH yield of 143.2 mg h g. and a competitive energy efficiency of 1.43 g kW h.
