Microwave Assisted Surfactant-Thermal Synthesis of Metal-Organic Framework Materials

Abstract

<jats:p>This research explores the application of surfactants as green solvents for the rapid microwave synthesis of metal-organic framework (MOF) materials. Lead, copper, and iron metal-organic framework materials were synthesized using surfactant-thermal microwave synthesis. The MOF materials were characterized by powder X-ray diffraction, infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis. With the exception of the iron MOF, which was expected to be amorphous, the MOF materials are crystalline, though generally exhibiting smaller crystals than those achieved with traditional solvothermal synthesis. This green synthetic method reduced synthesis time and reduced the use of traditional organic solvents as the reaction media.</jats:p>

Ultrafast Synthesis of Ultrathin Two-Dimensional Metal–Organic Framework Nanosheets with High Space-Time Yield

“…It is worth pointing out that the microwave-assisted route has demonstrated the ultrafast and uniform preparation of 3D MOFs, − 2D graphene oxide layers, and graphene quantum dots . However, reports on the use of microwave-assisted methods for synthesizing 2DMOFs remain very rare; there are only two examples based on porphyrin ligands with a large conjugated sheet. , Here, we have systematically studied the microwave-assisted synthesis parameters applying to Hf-BTB 2DMOFs and found that the fastest reaction time can be shortened to 2 min.…”

Metal–organic framework-based materials: emerging high-efficiency catalysts for the heterogeneous photocatalytic degradation of pollutants in water

“…The microwave-assisted method has the advantages of high crystallinity, time-saving and fast speed, but the morphology of the synthesized materials cannot be controlled. Compared with the traditional synthesis method, the MOF materials obtained via the microwave-assisted synthesis method have high crystallinity and porosity, 44 smaller crystal size, 45,46 and crystal defects. 47 In addition, the MOFs prepared via the microwave-assisted synthesis method possess uniform crystals, small volume and size, large pores, and large specific surface area.…”
