The effect of solution/free volume ratio on the MOF-5 characteristics

The influence of solution/free volume ratio on the specific surface area and pore volume of MOF-5 was investigated. MOF-5 was synthesized, by solvothermal reaction, using an identical starting mixture, at different solution/free volume ratio of 0.245, 0.807 and 3.429. The specific surface area decreased from 3018 m2/g to 2680 m2/g and 1099 m2/g respectively. The nitrogen adsorption capacity decrease in the same manner from 817.35 cm3/g to 740.75 cm3/g and 294.56 cm3/g respectively.
