研究の背景 Background


Chemical reactions, storage of energy, and diffusion/transportation take place in ‘space’ which exists in a variety of materials as inter-atomic space in crystal, pores of porous materials, or inter-space of particles/fibers. In order to develop new innovation which realizes sustainable society, the development of advanced technology of controlling ‘space’ is highly demanded in many fields, such as chemical reaction, separation, purification, energy storage/conversion, sensors, and bio-applications.

研究の目標 Outcome


Carbon materials have many advantages, such as light weight, electric conductivity, chemical/thermal stability, and high porosity. This research aims to develop carbon-based hybrid materials which have highly functionalized nanospace, and are useful for various applications, such as hydrogen storage, supercapacitors, secondary batteries, and fuel cells.
