Fabrication of Carbon Capsules with Hierarchical Pore Structures
Abstract:Carbon capsules with hierarchical pore structures were fabricated by using core–shell silica nanoparticles as templates and phenolic resin as a carbon precursor. Carbon capsules with hierarchical pore structures were obtained via in-situ polymerization of the phenolic resin on the surface of the silica nanoparticles followed by the carbonization and removal of the silica templates. The hierarchically pored carbon capsules exhibited multimodal porosity with a high specific surface area (∼1834 m2/g) and a large pore volume (∼1.83 cm3/g).
