Abstract

Abstract: The energy‐storage capacities of a series of water‐stable porous metal–organic frameworks, based on high‐valence metal cations (Al 3+, Fe 3+, Cr 3+, Ti 4+, Zr 4+ ) and polycarboxylate linkers, were evaluated under the typical conditions of seasonal energy‐storage devices. The results showed that the microporous hydrophilic Al‐dicarboxylate MIL‐160(Al) exhibited one of the best performances. To assess the properties of this material for space‐heating applications on a laboratory pilot scale with an open reactor, a new synthetic route involving safer, greener conditions was developed. This led to the production of MIL‐160(Al) on a 400 g scale, before the material was shaped into pellets through a wet‐granulation method. The material exhibited a very high energy‐storage capacity for a physical‐sorption material (343 Wh kg −1 ), which is in full agreement with the predicted value. Abstract : Some like it hot : The robust hydrophilic and microporous Al dicarboxylate MIL‐160(Al) is synthesized on the laboratory pilot scale, following an optimized environmentally benign synthesis route, and shaped as pellets. It is then evaluated under the conditions of a long‐term heat‐storage application, revealing that MIL‐160(Al) outperforms the best inorganic porous solids reported so far.
