SCAFFOLD-TRANSITION METAL HYDRIDE ION COMPOSITE FOR HYDROGEN STORAGE AND PREPARATION METHOD THEREFOR

摘要

The present invention relates to: a scaffold-transition metal hydride ion composite for hydrogen storage which is a hydrogen storage material for adsorbing hydrogen by Kubas binding, can safely and reversibly store hydrogen in a high capacity, shows more improved hydrogen storage characteristics and hardly causes structural collapse even if the adsorption and desorption of hydrogen is repeated; and a preparation method therefor. The a scaffold-transition metal hydride ion composite for hydrogen storage comprises: a scaffold material (SM) comprising a functional group introduced on the surface thereof; a Lewis acid which is bound on the scaffold material through the functional group; and a transition metal hydride ion which is bound to the Lewis acid.
