Description
Summary:The synthesis of a composite material with a hierarchical porous structure based on the metal-organic framework MIL-100 and a natural silica material diatomite is proposed in the present study. The structure of the synthesized materials was characterized by a complex of physical-chemical methods (low-temperature sorption of nitrogen, XRD, TG-DSC). The hierarchical porous structure of the composite was confirmed by the low-temperature nitrogen adsorption method. The presence of MIL-100(Fe) and diatomite phases (amorphous silica and quartz) was confirmed by XRD. The composite structure is stable up to 300°C (confirmed by TG-DSC). The sorption properties of the composite were evaluated in the removal of toluene vapor. The MIL-100(Fe)/diatomite composite exhibited the high adsorption capacity for toluene (183 mg/g).
