Lab Cooked MOF for CO₂ Capture: A Sustainable Solution to Waste Management

Abstract

To understand critical problems associated with solid waste and its consequences for the environment, a laboratory experiment is presented on the synthesis of aluminum-based metal−organic framework (MOF) MIL-53(Al) from household waste (PET bottles and aluminum foil/can), for undergraduate students of chemistry. This work is designed to teach students the research methodology and basic understanding of MOFs and their application in carbon capture and storage (CCS). Students also learnt several instrumentation techniques such as UV−vis spectroscopy, powder X-ray diffraction (P-XRD), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and gas sorption to characterize the physicochemical properties of . The facile production of MIL-53(Al) enabled the students to investigate its applicability in CO 2 sorption. The calculations of essential parameters such as CO 2 over N 2 selectivity and the use of statistical tools in data processing are also explained to the students. In the end, the instructor presented his/her feedback by evaluating the answer sheets (pre-and postlab work) and by demonstrating the overall lab work through a model presentation.

Upcycling hazardous metals and PET waste-derived metal–organic frameworks: a review on recent progresses and prospects

“…CO 2 adsorption capacity nearly matched with that of pristine MOF. 57 A Cu-MOF was synthesized in about 75% yield using copper-rich printed circuit boards and alkali reduction water from the textile industry, which contains a significant quantity of H 2 BDC (terephthalic acid). The molar ratio of copper and BDC surpassed 1 : 2, and the Cu-BDC impurities also increased.…”

Green self-activating synthesis system for porous carbons: Celery biomass wastes as a typical case for CO2 uptake with kinetic, equilibrium and thermodynamic studies

“…We explored different theoretical kinetic models for the kinetic study, including pseudo-first-order, pseudo-second-order, Elovich, and fractional order, models (Eqs. [8][9][10][11].…”

“…Recently, a variety of solid physical adsorbents, such as fullerene (B40) [8], metal-organic frameworks (MOFs) [9], carbon nanotubes [10], zeolites [11], porous carbon (PC) [12], graphene [13], and others have been developed to substitute traditional alkanolamines [14]. Because of their exceptional characteristics, MOFs and porous carbons received much interest.…”
