In this study, the effects of various methods of washing and drying of MOF-5 nanocrystals on structure forming have been investigated. Eight samples of MOF-5 were synthesized in different conditions. TGA, XRD and PSD analysis were applied to characterize of the samples. Methods of washing and drying were found to be important in determining the final structure of MOF-5s. MOF-5 with high BET surface area can be obtained by choosing a suitable method of washing and drying. According to the results obtained in this work, it was found that vacuum drying at 425 ºC is sufficient to desolvate the MOF-5-DMF. Similar results were obtained by washing (with CH2Cl2 and CHCl3) when compared with vacuum drying at 425 ºC according to XRD test. The pore size distribution of samples 1-5 and 8 were calculated by SHN1 method and results showed that the samples in which solvent vacuum was DMF, have lower pore volume, uniform pore size distribution and the their pore size are smaller than samples 3, 4 and 8. It was also found that activated MOF-5 can be converted to its deactivated form prior to drying of the samples.
