Direct Fabrication of Hierarchical Porous Carbonaceous Microparticles by Electron‐Beam Irradiation and Post‐Annealing of Polystyrene Colloidal Crystals
Abstract: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 wer… Show more
