INVESTIGATION OF HYDROGEN STORAGE PERFORMANCES OF SOME METAL ORGANİC FRAMEWORK STRUCTURED COMPOUNDS

Unlike other known storage systems, it is known that, hydrogen is capable of being absorbed in some storage media physically by means of weak van der waals interaction or by chemically. hydrogen can be stored in carbonnanotubes or in zeolites through physical absorption, or it can be stored in metal organicframeworks (mofs) which have higher surface area. in this study, in order for the solution of the weak aspect of hydrogen energy system, mixed ligand organometallic trans-diaquabis (nicotinamide-κn) bis(salicylato-κo) cobalt(ii), trans-diaquabis (3-hidroxybenzoato-κo1) bis(nicotinamide-κn1) cupper(ii), (p-brominbenzoato) bis (n,ndiethylnicotinamid) cobalt(ii) (a1, a2, a3 respectively) complexes are systeszed, then charactarized by tg, ftir, x-ray and elementel analysis, hydrogen storage performances are determined by adsorption. at the end of measurements it is found out that the synthesized compounds at 77k and under 90 bars pressure can store hydrogen wt% 2,59, 2,63 and 3,22 respectively.
