Co nanoparticles were generated to suppress the collapse of carbonized structures at high temperatures while catalytically inducing the formation of a hierarchical micro-mesoporous architecture within the carbon matrix. Concurrently， Nanjing。
but suffers from electrode fouling and pore blockage in real-world organically contaminated water. This work introduces a cobalt-nitrogen co-doped biomass-derived electrode (Co-NLE) designed to mitigate structural collapse and fouling in conventional electrodes through atomic-level Co-Nx coordination anchoring and hierarchical pore architecture. Characterization confirms that Co-Nx centers enhance carbon layer crosslinking。
