“…Previous reports suggested that nitrogen containing MIL 53(Cr) has an additional binding energy peak at 400 eV, however, here no peaks were observed at $400 eV, corresponding to nitrogen [24], in any of the spectra, which confirmed the absence of 2-MIM in the final product. Only C, O and corresponding metal signals were existed in the spectra [25][26][27][28]. Similar results were obtained using EDS elemental mapping (Fig.…”

“…The growing issue of climate change caused by high emissions of greenhouse gases (e.g., CO 2 , CH 4 ) became a motive for synthesizing MOFs with high gas adsorption capabilities. Several archetype MOFs, known as promising sorbents, such as MIL‐101, [ 128 ] UiO‐67, [ 129 ] UiO‐66, [ 130,131 ] MOF‐74, [ 132,133 ] MIL‐53, [ 134 ] MOF‐177 [ 135 ] and others [ 136,137 ] can be successfully prepared by a microwave‐assisted method. For example, Wu et al.…”

Usually, porous materials are synthesized by using conventional electric heating, which can be energy‐ and time‐consuming. Microwave heating is commonly used in many households to quickly heat food. Microwave ovens can also be used as powerful devices in the synthesis of various porous materials. The microwave‐assisted synthesis offers a simple, fast, efficient, and economic way to obtain many of the advanced nanomaterials. This review summarizes the recent achievements in the microwave‐assisted synthesis of diverse groups of nanoporous materials including silicas, carbons, metal–organic frameworks, and metal oxides. Microwave‐assisted methods afford highly porous materials with high specific surface areas (SSAs), e.g., activated carbons with SSA ≈3100 m2 g−1, metal–organic frameworks with SSA ≈4200 m2 g−1, covalent organic frameworks with SSA ≈2900 m2 g−1, and metal oxides with relatively small SSA ≈300 m2 g−1. These methods are also successfully implemented for the preparation of ordered mesoporous silicas and carbons as well as spherically shaped nanomaterials. Most of the nanoporous materials obtained under microwave irradiation show potential applications in gas adsorption, water treatment, catalysis, energy storage, and drug delivery, among others.

“…Such structures are not aggregated; instead, they have a more uniform particle size which is smaller than the sample obtained by the conventional hydrothermal method. According to the standard conditions required for MOF crystal growth, faster nucleation rates result in smaller crystal sizes 19 . Following the FESEM characterization results, the sonochemical synthesized MIL-53(Al) has smaller uniformly distributed nanoparticles mainly because of the accelerated nucleation and shorter synthesis time required for sonochemical synthesis.…”

The present study aims to investigate novel ultrasonic synthesized MIL-53(Al) and its applications in adsorption. Both conventional and ultrasonic methods were used to synthesized Mil-53(Al). The ultrasonic-assisted synthesis procedure results in reducing synthesis time to 24 hours; however, Compared to that conventional method takes 3 days to create the framework. Applying ultrasonic waves also increases surface area to 50% more than the ones synthesized by the conventional method, as well as creating the hierarchical MIL-53(Al) structure (meso- and micro-) pores. To this end, XRD, FESEM, BET, and FTIR analyses were employed to identify and characterize MIL-53(Al). The unique structure and high MIL-53(Al) yield lead to effective adsorption among MOF and lead ions. The optimum conditions for removing lead were 6.0 pH, 20 mg/l concentration, 60.0 min contact time, 0.04g adsorbent dose, and 318k temperature with 97.63% removal of the lead ions. The experimental adsorption equilibrium and kinetic data fitted the Langmuir isotherm and pseudo-second-order kinetic models, respectively. Moreover, the use of ultrasonic synthesized MIL-53(Al), for the first time as a novel adsorbent in heavy metal removal, pointed to the great potential of this new environmentally-friendly adsorbent in removing lead ions from aqueous solutions.
