Investigating the effect of time on the morphology and crystallinity ofMIL-۱۲۵ in the solvothermal synthesis method

The use of metal-organic frameworks(MOFs) is constantly expanding. MIL-۱۲۵ is one of themost important and widely used cases [۱]. Several methods have been reported for the synthesisof this framework, such as the use of reflux and autoclave in solvothermal synthesis [۲]. Synthesistime is one of the most important parameters in synthesis, which includes energy consumption andtime, which are two important parameters in research. In this research, the synthesis of MIL-۱۲۵was done by solvothermal method, and in an autoclave, we specifically investigated the effect oftime on morphology and crystallinity. Our results showed that the ۲۴-hour synthesis had the bestresults among the times of ۶, ۱۲, ۱۸, and ۲۴h. These results were also checked with ۷۲-hour timeand reflux conditions, which most of the syntheses are reported in the reports with this method,and it was shown that ۲۴-hour time with autoclave had a favorable and acceptable result [۳]. Thismeans that there is an acceptable improvement in time and energy.
