Synthesis and hydrogen adsorption in Cu-based coordination framework materials

Cu-4,4′-(perfluoropropane-2,2-diyl)diphthalic acid coordination compounds were synthesized using Cu(OH)2 and CuSO4, and their thermal and hydrogen sorption properties were characterized. The formation of the organometallic compound using Cu(OH)2 was found to proceed at a noticeably higher rate, and this complex was more stable. Both Cu complexes showed relatively high hydrogen adsorption capacities of about 0.35–0.45 wt.% at room temperature and hydrogen pressure of 10–11 atm.
