Özet

Three boric acid mediated metal organic frameworks were synthesized by solution method with using succinic acid, fumaric acid and acetylene dicarboxylic acid as a ligand source and sodium as a metal source. The complexes were characterized by FT-IR, powder XRD, elemental analyses and single crystal measurements. The complexes with the formula, C4H18B2Na2O14, C4H16B2Na2O14 and C4H14B2Na2O14 were successfully obtained. BET surface area of complexes were calculated and found as 13.474 m(2)/g for catena-(tetrakis(mu 2-hydroxo)-(mu 2-trihydrogen borate)-(mu 2-succinato)-di-sodium boric acid solvate), 1.692 m(2)/g for catena-(tetralds(mu 2-hydroxo)-(mu 2-trihydrogen borate)-(mu 2-fumarato)-di-sodium boric acid solvate) and 5.600 m(2)/g for catena-(tetrakis(mu 2-hydroxo)-(mu 2-trihydrogen borate)-(mu 2-acetylenedicarboxylato)-di-sodium boric acid solvate). Hydrogen storage capacities of the complexes were also studied at 77 K 1 bar pressure and found as 0.108%, 0.033%, 0.021% by mass. When different ligands were used, the pore volume, pore width and surface area of the obtained complexes were changed. As a consequence, hydrogen storage capacities also changed.
