Abstract
In this literature, it was successfully prepared metal-organic framework MIL-53(Al) for the first time at convenient conditions using sonication irradiation. Comparison of Sonochemical-assisted hydrothermal synthesis with conventional hydrothermal method had been investigated. Suitable morphology and unique porosity properties were obtained through Sonochemical-assisted approach, which has presented excellent features and good thermal stability for crystals samples with nano-sized particles versus the conventional hydrothermal method. Low reaction temperature of 150 °C and short time of synthesis 6 h investigated pure crystallinity of MIL-53(Al) via Sonochemical-assisted synthesis due to its ability to supply controlled amounts of energy to the solution that leads to increase nucleation rate and crystal growth. The characterization of samples was specified using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Nitrogen Adsorption Technique (BET) and Thermal Gravimetric Analysis (TGA). Highest surface area is nearly to 1363.5 m2/g, best thermal stability up to 600 °C, more uniform and narrower size distribution in the range of 0.7–0.93 μm at short sonication time 24 h and low temperature at 150 °C were observed.
