POROUS CRYSTAL WITH AMMONIABORANE AND PRODUCING THEREOF

摘要

PURPOSE: A porous crystal containing ammonia borane is provided to use hydrogen storage ability of ammonia borane and to simplify regeneration process. CONSTITUTION: A porous crystal contains ammonia borane which is chemically combined to a crystalline structure. The porous crystalline structure is metal-organic framework structure or covalent bond organic framework structure. The metal-organic framework structure contains an organic ligand and metal ion. The organic ligand is chemically combined two or more metal ion. The metal-organic framework structure is denoted by chemical formula 1. A method for preparing the porous crystal comprises: a step of preparing the metal-organic framework structure containing a primary amine or covalent bond organic framework structure; and a step of adding borane or borane derivative to the porous crystal.
