We are designing and developing novel nanocarbon materials together with their hybrids by controlling the reaction nano-fields for the syntheses of these materials. One example is fully tailored carbon nanotubes with uniform diameter and length. Another noteworthy material is zeolite-templated carbon which has structure regularity like zeolite and a surprisingly large surface area up to 4000 m2/g. In addition, we have recently developed a method for a complete coating of the entire surface of mesoporous silica with graphene layers. We are trying to apply these unique nanomaterials to electronic device, electrochemical capacitors, lithium-ion batteries, hydrogen storage, biosensors and capsules for drug and gene delivery.
