A Metal-Free Catalyst: Sulfur-Doped And Sulfur Nanoparticle-Modified Cmk-3 As An Electrocatalyst For Enhanced N-2-Fixation

Carbon-based electrocatalysts have attracted considerable attention owing to their structural tunability and green sustainability. However, the simultaneous adjustment of active sites and suppression of HER of carbon-based catalysts still remains a challenge. Herein, CMK-3 was doped with sulfur and its surface was modified with sulfur nanoparticles by a one-pot method and used as the electrocatalyst for N-2-fixation.
