Highly effective catalysts are of great importance for artificial nitrogen fixation. Inspired by the natural nitrogenase, we biomimetically designed an inorganic catalyst, Mo(IV)-doped FeS2, for electroreduction of dinitrogen to ammonia. The Mo(IV) ions favor the adsorption and activation of N2, while the FeS2 substrate depresses the competitive hydrogen evolution reaction, and the two factors jointly endow the catalyst with a high Faraday efficiency of 14.41% at −0.2 V versus RHE.

Mo（IV）掺杂的FeS 2催化剂的仿生设计，用于将二氮电还原为氨
高效催化剂对于人工固氮非常重要。受天然固氮酶的启发，我们仿生设计了一种无机催化剂，掺杂了Mo（IV）的FeS 2，用于将二氮电还原为氨。Mo（IV）离子有利于N 2的吸附和活化，而FeS 2底物抑制竞争性氢释放反应，并且这两个因素共同赋予催化剂在相对于RHE的-0.2 V下具有14.41％的高法拉第效率。
