The paper is focused on the method of preparation of MOF-carbon composite materiál (MOF@HPCM), whichcan be used as an effective material for adsorption and storage of carbon dioxide in the future.A hierarchically porous carbon monolith (HPCM) [1] with a suitable surface treatment was used for thepreparation of the composite material, in the pores of which MOF materials – HKUST-1 (Cu), MOF-76 (Gd) andMIL-101 (Fe) were crystallized. Characterization of composites using scanning electron microscopy (SEM) andsubsequent Thermogravimetric analysis (TG) confirmed the presence of MOF materials. The parent materialsand the resulting composites were subjected to carbon dioxide sorption at 273 K to obtain the adsorbed amountand then at 288 K and 303 K to calculate isosteric heat (-QISO).Sorption experiments showed the most promising composite HKUST-1 (Cu)@HPCM-OH, whose sorptioncapacity at 273 K increased from 1.87 mmol/g to 2.42 mmol/g compared to the original material (HPCM-OH),while the isosteric heat (-QISO) remained almost unchanged compared to the parent material – 30.65 kJ/mol forHPCM-OH and 29.66 kJ/mol for HKUST-1 (Cu)@HPCM-OH. More detailed information will be presented inthe form of a poster.
