Zr-Fumarate MOF a Novel CO2-Adsorbing Material: Synthesis and Characterization

Abstract

A novel Zr-fumarate (Zr-fum) metal organic framework was synthesized by the reaction of zirconium chloride and fumaric acid under solvothermal conditions without a formic acid modulator. The synthesized material was characterized by the powder X-ray diffraction, Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and Brunauer-Emmett-Teller (BET) techniques. The results of powder XRD showed the presence of amorphous and crystalline phases. The surface area and average pore diameter of the material were found to be 205.49 m 2 /g and 2.12 nm, respectively, and TGA showed that the material was stable up to 300°C. The CO 2 adsorption properties of the Zr-fum MOF revealed an uptake of 8 wt% at room temperature (25°C) and atmospheric pressure. The cyclic CO 2 sorption study showed the complete recyclability of the synthesized material, suggesting that the material has potential for use in gas sorption and separation.

Challenges and Perspectives on Carbon Fixation and Utilization Technologies: An Overview

“…2 shows various approaches to capturing CO 2 from flue gas or air. Typically, CO 2 capture technologies can be classified into several categories: (1) absorption using alkaline solutions (Yu et al, 2012;Lin and Chu, 2015); (2) adsorption using zeolite (Lee et al, 2013), activated carbon , and metal organic frameworks (Ganesh et al, 2014); (3) mineral carbonation using natural ores and/or solid wastes (Olivares-Marín and Maroto-Valer, 2012); (4) selective membrane Ramasubramanian et al, 2013); (5) cryogenic (Wang and Gan, 2014); (6) high-temperature solid looping processes such as calcium looping (Chang et al, 2013) and chemical looping (Chiu and Ku, 2012); (7) ionic liquid (Zhang et al, 2012); and (8) biological including microalgae and enzymebased processes (Klinthong et al, 2015). Some of the above capture technologies, such as mineral carbonation and biological methods, are directly related to utilization or conversion because the physicochemical property of CO 2 is changed after capture.…”

Activated MIL-53(Al) for Efficient Adsorption of Dichloromethane and Trichlormethane

“…The equilibrium conformation state with a given temperature and pressure depends on the loading of guest molecules. The breathing transitions between lp and np phases are spontaneous process upon the adsorbed molecules, such as CO 2 (Rallapalli et al, 2010;Ganesh et al, 2014) and H 2 O (Chen et al, 2013). Loaded molecules induce a significant stress inside the elastic framework that is in the order of several to tens of MPa.…”

“…Among these techniques, adsorption is one of the most effective technique for VOCs removal. Porous materials including zeolites, resins, and activated carbons are the most frequently utilized adsorbents (Ganesh et al, 2014;Dai et al, 2015;de Fonseca et al, 2015;Palau et al, 2015). Metal-organic frameworks (MOFs), which are constructed of metal ions and organic linkers, have attracted considerable interests due to their high porosity and large adsorption capacity (Ren et al, 2015;Xu et al, 2015).…”

“…For example, CO, can be recycled through the photocatalytic reduction of CO 2 into hydrocarbon fuels . CO, can also be absorbed by special materials, such as Zr-Fumarate MOF (Ganesh et al, 2014). In Nature, CO, can be stored in sea rocks and trees.…”
