A novel microwave assisted reverse micelle fabrication route for Th (IV)‐MOFs as highly efficient adsorbent nanostructures with controllable structural properties to CO and CH₄ adsorption: Design, and a systematic study

Abstract

Reducing gas contaminants by affordable and effective adsorbents is a major challenge in the 21st century. In the present study, thorium metal organic framework (Th‐MOF) nanostructures are introduced as highly efficient adsorbents. These compounds were manufactured via a novel route resulting from the development of microwave assisted reverse micelle (MARM) and ultrasound assisted reverse micelle (UARM) methods. The products were characterized utilizing XRD, SEM, TGA/DSC, BET, and FT‐IR analyses. Based on the results, the samples synthesized by MARM had uniform size distribution, high thermal stability, and significant surface area. Calculations using DFT/B3LYP indicated that the compounds have a tendency to the polymeric form, which could theoretically confirm the formation of Th‐MOF. Results of analysis of variance (ANOVA) showed that synthesis parameters played a critical role in the manufacturing of products with distinctive properties. Response surface methodology (RSM) predicted the possibility of creating Th‐MOF adsorbents with the surface area of 2579 m2/g, which was a considerable value in comparison with the properties of other adsorbents. Adsorption studies showed that, in the optimum conditions, the Th‐MOF products had high adsorption capacity for CO and CH4. It is believed that the synthesis protocol developed in the present study and the systematic studies conducted on the samples which lead to products with ideal adsorption properties.

“…It would appear that the synthesis method has a significant effect on the morphology of samples, but our efficient route proved to be capable of producing nanoparticles with homogeneous morphology in a relatively short time. The observed effects of microwave irradiation on Fe-MOF@Fe 3 O 4 morphology were similar to those seen in previous studies ( Sargazi et al, 2018 ; Sargazi et al, 2019 ).…”

“…Among these, voltammetry is the proposed method for bypassing such problems due to its unique advantages such as rapid response, inherent selectivity, great sensitivity, simplicity, cost-effectiveness, and relatively short analysis time to determine organic molecules such as drugs and relevant molecules in biological fluids and pharmaceutical doses (Maaref et al, 2018;József et al, 2019;Salajegheh et al, 2019; Sargazi et al, 2019;Shetti et al, 2019;Kulkarni et al, 2020;Malode et al, 2020;Vakili Fathabadi et al, 2020;Liu et al, 2021a;Foroughi et al, 2021;Obireddy and Lai, 2021;Obireddy and Lai, 2022). An effective strategy to increase the electrochemical performance of sensors is to design composites by integrating highly electrocatalytic active materials with excellent conductivity materials, resulting in the electrode surface modification (Zhang et al, 2016;Foroughi and Ranjbar, 2017;Shetti et al, 2018;Fathi et al, 2020;Azizabadi et al, 2021;Liu et al, 2021b;Liang et al, 2022;Qi et al, 2022).…”
