Plasma-assisted NH3 synthesis has recently emerged as a promising complementary approach to the Haber-Bosch process for decentralized and sustainable NH3 production. Here, we introduce an ingenious catalyst design strategy featuring "dual vacancies" that significantly enhances the Mars-van Krevelen (MvK) pathway on a TiN/TiO2 catalyst, enabling high-efficiency NH3 production under mild conditions. Using this strategy, we achieved a superhigh NH3 yield of 226.3 mg h-1 gcat.-1, surpassing the catalytic activity of most reported catalysts.
