Abstract

Nanoporous carbon particles with magnetic Co nanoparticles (Co/NPC particles) are synthesized by one‐step carbonization of zeolitic imidazolate framework‐67 (ZIF‐67) crystals. After the carbonization, the original ZIF‐67 shapes are preserved well. Fine magnetic Co nanoparticles are well dispersed in the nanoporous carbon matrix, with the result that the Co/NPC particles show a strong magnetic response. The obtained nanoporous carbons show a high surface area and well‐developed graphitized wall, thereby realizing fast molecular diffusion of methylene blue (MB) molecules with excellent adsorption performance. The Co/NPC possesses an impressive saturation capacity for MB dye compared with the commercial activated carbon. Also, the dispersed magnetic Co nanoparticles facilitate easy magnetic separation.
