“…To remove these dye‐stuffs from water, activated carbon has been intensively studied and widely used as an efficient adsorbent. The adsorption capacity of activated carbon changes from 9.4 to 300 mg · g −1 , which is determined by a starting material, an activation method, and a heat treatment condition, etc . Although activated carbon is widely used as an adsorbent, it is still expensive due to the complicated production procedures and a high‐cost facility maintenance .…”

A novel approach to fabricate hierarchical porous carbonaceous microparticles (HPCMs) by electron irradiation of polystyrene (PS) colloidal crystals followed by annealing is presented. Electron irradiation transforms PS spheres into hydrogenated amorphous carbon and post‐annealing further graphitizes the irradiated PS. Colloidal crystals consist of regularly ordered mesopores and electron irradiation and post‐annealing create new micropores on the surfaces of PS spheres. Consequently, PS colloidal crystals were transformed into carbonaceous materials comprising mesopores and micropores. Through mechanically grinding the colloidal crystals, HPCMs are fabricated. Due to comparatively high surface areas and graphitic structures, the HPCMs exhibit moderate adsorption properties for methyl orange in an aqueous solution.
