Fabrication of Carbon Capsules with Hollow Macroporous Core/Mesoporous Shell Structures

Carbon capsules with hollow core/mesoporous shell (HCMS) structures have been synthesized (see Figure for schematic) for the first time using solid core/mesoporous shell (SCMS) silica spheres as templates. The capsules have bimodal pore systems consisting of a uniform, tunable, hollow macroscopic core and a mesoporous shell, thus leading to a great variety of possible applications.
