“…Compared with M0, spectra of M1–M5 had new characteristic peaks at 768 cm −1 , which were attributed to the stretching vibration of ZrO. Similar results have been also reported in other works 55‐58 . With an increase of UiO‐66‐(COOH) 2 content, the intensity of the peak at 768 cm −1 increased, indicating that the UiO‐66‐(COOH) 2 nanoparticles had been successfully blended in these membranes.…”

BACKGROUND: Developing new materials for separating Sr 2+ ions from aqueous solutions is significant. Metal-organic frameworks are regarded as excellent adsorption materials due to their high specific surface area and abundant adsorption sites. In this work, a novel UiO-66-(COOH) 2 -based mixed matrix membrane (MMM) was prepared by combining UiO-66-(COOH) 2 with polyethersulfone (PES) for separating Sr 2+ . RESULTS: The MMMs were characterized using scanning electron microscopy, Fourier transform infrared spectroscopy and water contact angle and water flux measurements. Various contents (0-2.5 wt%) of UiO-66-(COOH) 2 were blended into PES membranes. The results showed that incorporating UiO-66-(COOH) 2 significantly increased membrane porosity and water flux, and reduced contact angle. The membrane (M4) that contained 2.0 wt% UiO-66-(COOH) 2 exhibited an excellent morphology and the highest Sr 2+ uptake capacity (111.9 ∼g cm −2 ). Adsorption kinetics and isotherms showed that the nature of the adsorption of the membrane towards Sr 2+ was chemisorption, homogeneous and monolayer. Compared with the adsorption capacity of UiO-66-(COOH) 2 towards Sr 2+ in adsorption packed column, these values of M4 decreased by about 75% during membrane filtration. The rejection performance of MMMs increased with increasing UiO-66-(COOH) 2 content. Breakthrough curves of MMMs were not correlated with flow rate in the range of 10-180 mL h −1 . The presence of Ca 2+ and Mg 2+ ions did not obviously affect the separation of Sr 2+ , but Pb 2+ had a significant influence. Furthermore, after five adsorption-desorption experiments, the regeneration remained at about 95% of initial values. CONCLUSIONS: The MMMs showed good adsorption capacity for Sr 2+ and exhibited favorable reusability and stability.

“…Among them, MOF801 possesses a high Zeta potential value (+18.6 mV), and as the mass ratio of LiPF 6 : MOF801 in anhydrous ethanol increases from 0:1 to 12:1, the Zeta potential decreases from 18.6 to 0.839 mV, which indicates that partial positive charges in the solution are neutralized because MOF801 tends to adsorb anions (PF 6 − ). [51] In general, the Raman spectra and zeta potential results demonstrate that MOF801 can adsorb PF 6…”

A practical and effective approach to improve the cycle stability of high‐energy density lithium metal batteries (LMBs) is to selectively regulate the growth of the lithium anode. The design of desolvation and lithiophilic structure have proved to be significant means to regulate the lithium deposition process. Here, a fluorinated polymer lithiophilic separator (LS) loaded with a metal–organic framework (MOF801) is designed, which facilitates the rapid transfer of Li+ within the separator owing to the MOF801‐anchored PF6− from the electrolyte, Li deposition is confined in the plane resulting from the polymer fiber layer rich in lithiophilic groups (C─F). The numerical simulation results confirm that LS induces a uniform electric field and Li+ concentration distribution. Visualization technology records the behavior of regular Li deposition in Li||Li and Li||Cu cells equipping LS. Therefore, LS exhibits an ultrahigh Li+ transference number (tLi+ = 0.80) and a large exchange current density (j0 = 1.963 mA cm−2). LS guarantees the stable operation of Li||Li cells for over 1000 h. In addition, the LiNi0.8Co0.1Mn0.1O2||Li cell equipped with LS exhibits superior rate and cycle performances owing to the formation of LiF‐rich robust SEI layers. This study provides a way forward for dendrite‐free Li anodes from the perspective of separator engineering.

“…7 More electrons need to be transferred in the process of the oxygen evolution reaction, which makes it difficult to achieve mass production of hydrogen in practical application. 8 The key to water electrolysis lies in the selection of electrode catalytic materials. At present, commercial catalysts are mainly precious metals, but precious metals have low reserves and high cost.…”
