Electrochemical nitrogen fixation provides a sustainable alternative to the Haber-Bosch technique. Herein, nanoporous AuCu alloys are fabricated with more active sites and accessible channels, which promote N absorbability and activation. Our catalyst displays superior efficiency of 45.7%, ammonia yield of 25.7 μg h cm and selectivity of 98%, overcoming solid Au and Cu nanoparticles.
电化学固氮为哈伯-博施法提供了一种可持续的替代方法。在此，制备了具有更多活性位点和可及通道的纳米多孔金铜合金，这促进了氮的吸收和活化。我们的催化剂显示出45.7%的卓越效率、25.7 μg h cm的氨产率和98%的选择性，优于固态金和铜纳米颗粒。
