Porous Coordination Polymers and Aluminophosphates transform water adsorptive heat to drive solar cooling and heating

Abstract:
We present a recent work [1-4] on novel aluminum-based sorbent porous materials for solar thermally driven cooling and heating processes. Such applications constitute an efficient system for adsorptive heat transformation of clean and renewable sorbates (e.g. water) within these materials. The regeneration part of the thermodynamic cycle of the system requires desorption of the sorbate at elevated temperatures, utilizing solar energy thereby minimizing primary energy consumption and carbon emissions. Our studies comprise a combination of experimental and computational techniques; hydrothermal cycle experiments, in-situ powder X-ray diffraction analysis, in-situ second harmonic generation microscopy experiments, pulsed field gradient NMR measurements, density-functional theory computations, Monte Carlo and molecular dynamics simulations, and a Widom-type scheme. The studied Al-frameworks exhibit high uptake capacity and fast kinetics for water sorbate, and the ability to withstand the harsh conditions imposed during repeated water sorption/desorption cycles in heat-pumping and cooling applications with no loss of crystallinity or porosity and no degradation of the framework. Our studies highlight the aluminum-based sorbents coded as CAU-10-H, MIL-100 and SAPO-34 among the most promising next-generation adsorbents for thermally driven cooling and heating applications.
