Comarine Derivatives Designed as Carbon Dioxide and Hydrogen Storage

Abstract

The growing of fossil fuel burning leads to increase CO2 and H2 emissions, which cause increasing of global warming that, has brought big attention. As a result, enormous researches have been made to reduce CO2 and H2 build up in the environment. One of the most promising approaches for managing CO2 and H2 gases percentage in the atmosphere is capturing and storage them inside proper materials. Therefore, the design of new materials for carbon dioxide and hydrogen storage has received increasing research attention. Four derivatives of coumarine linked to thiazolidinone were synthesized in good yields by reacting 3-(2-Phenylaminoacetyl)coumarine and 2-phenylimino thiazolidinone-4-one in a solution of anhydrous sodium acetate /glacial acetic acid at 120° for 5-6 hours. The synthesised organic compounds were identified by using different techniques such as 1H NMR, 13C NMR, FTIR, and energy dispersive X-ray spectra. The agglomeration, shape and porosity of the particles were determined utilizing scanning electron microscopy (SEM) and microscopy images analysis. The capacity of carbon dioxide (CO2) and hydrogen (H2) adsorption on the prepared organic materials at 323 K, 50 bar ranged from 22 to 31 cm3 /g, and hydrogen from 4 to 12 cm3 /g for the four synthesised compounds which contain phenyl substituted with chloro, nitro and bromo groups was found to be the most active adsorbent surfaces for carbon dioxide and hydrogen storage.
