Facility Green Electrocatalyst: Sulfur-Modified N-Doped Durian Shell Derived Graphene-like Porous Carbon for N₂ Fixation

Undoubtedly, electrochemical ammonia synthesis without carbon footprint will be an anticipated alternative to the Haber-Bosch N₂-fixation process which is energy-intensive. Herein, the durian shell derived carbon was designed as the electrocatalyst precursor, and its graphene-like morphology features and unique hierarchic pore structure obtained by controlling calcination condition was used to trap the N₂ molecules firmly and convert them. Furthermore, the NH₃ synthesis properties with N, S doping and co-doped were systematically tested. Detailed investigations shown the synergistic effect brought by N and S atom double doping strategy was efficient promote the increase of electrochemical active sites and thus enhanced the electrocatalytic performance. The NH₃ yield of 32.05 µg_NH3mg_cat. ⁻¹ h^− 1 was obtained by double-doped strategy, which enriched the application of biomass derived carbon materials.
