Abstract
Zeolite-templated carbon (ZTC), prepared by using zeolite as a template, has a regularly-arrayed and mutually connected pore structure with uniform pore size (1.2 nm) because ZTC is a negative replica of template zeolite. Its framework is comprised of backybowl-like curved nanographenes linking each other and ZTC has a high surface area capable of adsorbing large amount of molecules and ions. Moreover, its three-dimensionally connected and regularly-arrayed pore structure decreases the ion diffusion resistance of molecules and ions. By taking its advantage, it is expected that ZTC can be used for high hydrogen storage materials and electrodes of electrochemical capacitors with high energy and power densities. In this study, we report high electrochemical performances of ZTC as an electrode material in both organic and aqueous electrolytes. Next, we report hydrogen storage properties of ZTC combinded with an organo-platinum complex.
