Summary: Metallic particles can inhibit the demetalation of Fe SACSs by acting as electron donors and strengthening the Fe-N bond, thereby preventing electrochemical Fe dissolution. Different types, forms, and contents of metal particles have varying effects on the Fe-N bond strength. Screening a particle-assisted Fe SACS resulted in a 78% reduction in Fe dissolution and enabled continuous operation for up to 430 hours in a fuel cell.

Summary: Fluorine pollution is a major global concern, and metal-organic frameworks (MOFs) have unique chemical reactivity and broad functionalities as potential fluoride adsorbents. However, their application is limited by instability and difficult separation. In this study, a lotus flower-like Al/N-doped porous carbon composite was prepared using Al-based MOF as a precursor and was used for capacitive deionization (CDI) defluorination. The carbon material derived from the MOF showed a larger specific surface area and N-rich structure, as well as multiple F- capture sites. Through the CDI defluorination system, F- was rapidly captured under the synergistic effect of metal sites and carbon substrate. The maximum F- removal capacity was 76.28 mg g(-1) at 1.2 V, and the adsorption kinetics followed a pseudo-second-order model. This electroenhanced adsorption method showed high adsorption capacity and selectivity for F-.

Summary: This study investigates the relationship between crystal microstructures of intercalation electrodes and desalination performance in the presence of naturally occurring organic matters (NOM), with a focus on the impact of humic acid (HA). The results show that HA has contrasting effects on the ion storage performances of tunnel and layered sodium manganese oxides (T-NMO and L-NMO) electrodes. HA causes capacity fading in T-NMO electrodes due to crystal lattice contraction, hinderance of ions diffusion, and electrode dissolution. On the other hand, HA insertion enlarges the interlayer distance and diminishes electrode dissolution in L-NMO electrodes, resulting in an improvement of ion storage capacity. These findings provide important guidance for the design and deployment of CDI in real-world applications.
