Abstract
AbstractA new ZrIV mesaconate framework material was synthesized by heating a mixture of ZrCl4, mesaconic acid, and acetic acid in a molar ratio of 1:1:30 in DMF at 150 °C for 24 h. The influence of the molar ratio of ZrCl4/acetic acid on the crystallinity of the compound was examined. The as‐synthesized compound was Soxhlet‐extracted with ethanol and subsequently heated under vacuum to remove guest solvent molecules from the pores. Both the as‐synthesized sample and the thermally activated sample of this new material were characterized by X‐ray powder diffraction (XRPD), FTIR spectroscopy, thermogravimetry, and elemental analysis. The compound is thermally stable up to 320 °C under air. XRPD experiments indicate that the compound maintains its crystallinity upon exposure to water, acetic acid, and 1 M HCl. According to the N2 sorption analyses, the compound possesses a BET surface area of 662 m2 g–1. Thus, the material is a promising candidate for gas storage and separation owing to its high physiochemical stability and considerable porosity.
