- Аннотация: A MIL-125 metal–organic framework structure was synthesized from titanium and 1, 4-benzenedicarboxylicacid. The specific micropore volume of the synthesized sample was found to be W0 = 0.59 cm3/g,and the specific BET surface area was SBET = 1320 m2/g. Analysis of the synthesized material revealed the possibilityof its application for accumulating energetically important gases: methane and hydrogen. The adsorptionof hydrogen and methane on MIL-125 was experimentally studied within the temperature range of 77−293 Kfor hydrogen and 213−293 K for methane at absolute pressures up to 1.5 bar. The high heats of methane andhydrogen adsorption on the synthesized sample of about 26 and 14 kJ/mol were evaluated. It was found that,due to narrow pores, the adsorbent may be effective in accumulating methane at high temperatures. MIL-125exhibited the best adsorption performance for hydrogen. At the temperature of 77 K and atmospheric pressure,the sample can accumulate up to 2.3 wt % hydrogen.
