Facility Green Electrocatalyst: Sulfur-Modified N-Doped Durian Shell Derived Graphene-like Porous Carbon for N2 Fixation
Journal of Inorganic and Organometallic Polymers and Materials(2024)
Abstract
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 µgNH3mgcat. −1 h− 1 was obtained by double-doped strategy, which enriched the application of biomass derived carbon materials.
