“…This deviation is most probably attributed to the formation of ligand defects. Remarkably, an additional contribution was observed in the PSD plot for Zr-Fum HT at ∼1.12 nm which may be associated with the formation of Zr 6 cluster defects as previously suggested. ,− …”

Adsorption-driven heat transfer devices incorporating an efficient “adsorbent–water” working pair are attracting great attention as a green and sustainable technology to address the huge global energy demands for cooling and heating. Herein, we report the improved heat transfer performance of a defective Zr fumarate metal–organic framework (MOF) prepared in a water solvent (Zr-Fum HT). This material exhibits an S-shaped water sorption isotherm (P/P 0 = 0.05–0.2), excellent working capacity (0.497 mLH2O mL–1 MOF) under adsorption-driven cooling/chiller working conditions (T adsorption(ads) = 30 °C, T condensation (con) = 30 °C, and T desorption(des) = 80 °C), very high coefficient of performances for both cooling (0.83) and heating (1.76) together with a relatively low driving temperature at 80 °C, a remarkable heat storage capacity (423.6 kW h m–3 MOF), and an outstanding evaporation heat (343.8 kW h m–3 MOF). The level of performance of the resultant Zr-Fum HT MOF is above those of all existing benchmark water adsorbents including MOF-801 previously synthesized in the N,N-dimethylformamide solvent under regeneration at 80 °C which is accessible from the solar source. This is coupled with many other decisive advantages including green synthesis and high proven chemical and mechanical robustness. The microscopic water adsorption mechanism of Zr-Fum HT at the origin of its excellent water adsorption performance was further explored computationally based on the construction of an atomistic defective model online with the experimental data gained from a subtle combination of characterization techniques.

“…14 Here we report three Zr(IV)-based MOFs using 4,4 0 -stilbenedicarboxylic acid and 2,2 0 -diamino-4,4 0 -stilbenedicarboxylic acid as linkers, with one of them synthesized using a non-traditional mixed-linker approach, showing one of the highest (up to 4.9 wt%) hydrogen uptakes measured among the Zr-based MOFs reported to date. 14,15,17,18 In addition, high selectivity of CO 2 adsorption over nitrogen was also observed for UBMOF-31. Solvothermal reactions of 2,2 0 -diamino-4,4 0 -stilbenedicarboxylic acid (DASDCAH 2 ) and 4,4 0 -stilbenedicarboxylic acid (SDCAH 2 ) with ZrCl 4 and benzoic acid (modulator) in a mixture of dimethylformamide (dmf) and…”

Mixed-linker approach in designing porous zirconium-based metal–organic frameworks with high hydrogen storage capacity

et al. 2016

Three highly porous Zr(iv)-based metal-organic frameworks, UBMOF-8, UBMOF-9, and UBMOF-31, were synthesized by using 2,2'-diamino-4,4'-stilbenedicarboxylic acid, 4,4'-stilbenedicarboxylic acid, and combination of both linkers, respectively. The mixed-linker UBMOF-31 showed excellent hydrogen uptake of 4.9 wt% and high selectivity for adsorption of CO2 over N2 with high thermal stability and moderate water stability with permanent porosity and surface area of 2552 m(2) g(-1).

“…The implementation of both strategies allows full control of both the functionality and the porosity of the synthesized POPs. Furthermore, it has been reported that porous polymeric materials with tetrahedral geometry have a high surface area, porosity, rigidity, and gas adsorption capacity [32][33][34][35][36][37].…”

The design and synthesis of new multifunctional organic porous polymers has attracted significant attention over the years due to their favorable properties, which make them suitable for carbon dioxide storage. In this study, 2-, 3-, and 4-hydroxybenzaldehyde reacted with phenyltrichlorosilane in the presence of a base, affording the corresponding organosilicons 1–3, which further reacted with benzidine in the presence of glacial acetic acid, yielding the organic polymers 4–6. The synthesized polymers exhibited microporous structures with a surface area of 8.174–18.012 m2 g−1, while their pore volume and total average pore diameter ranged from 0.015–0.035 cm3 g−1 and 1.947–1.952 nm, respectively. In addition, among the synthesized organic polymers, the one with the meta-arrangement structure 5 showed the highest carbon dioxide adsorption capacity at 323 K and 40 bar due to its relatively high surface area and pore volume.
