The energy-storage capacities of a series of water-stable porous metal-organic frameworks, based on high-valence metal cations (Al , Fe , Cr , Ti , Zr ) 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 ), which is in full agreement with the predicted value.

“…Figure 5A shows H 2 O adsorption isotherm of BFWLAND and SG. The composite exhibited the characteristics of Type-III isotherm, whereas SG showed typical Type-IV isotherm pattern [10]. As evident from the figure, unlike typical Type III materials, BFWLAND has shown excellent adsorption capacity over a wide range of relative pressure.…”

Wasseradsorption an porösen Materialien bietet Möglichkeiten, das gesteigerte Komfortbedürfnis der Menschheit zu adressieren: Sorptionsgestützte Klimatisierung, Entfeuchtung und Wassergewinnung aus der Umgebungsluft. In vorliegender Arbeit werden drei neuartige Adsorbentien, die zwei MOFs Aluminium-Fumarat und CAU-10-H, sowie ein PMO mit Blick auf die Anwendung charakterisiert. Die maximale Wasserbeladung der Materialien liegt zwischen 0,35 und 0,52 g g -1 .Für verschiedene Anwendungen wurde der Umsatz berechnet und in einem Eigenaufbau die Stabilität der Materialien über 300 Zyklen untersucht.Water adsorption on porous materials offers opportunities to address the increased comfort needs of mankind: sorptionassisted air-conditioning, dehumidification, and water extraction from ambient air. In the present work, three novel adsorbents, two MOFs aluminum fumarate and CAU-10-H, as well as a PMO with regard to the application are characterized. The maximum water loading of the materials is between 0.35 and 0.52 g g -1 . The water exchange was calculated for various applications and the stability of the materials was investigated in a self-assembled test setup over 300 cycles.Abbildung 7.
