The presence of selenium vacancies (V Se ) in metal selenides enables the activation of peroxymonosulfate (PMS) for efficient water purification. However, the mechanisms of interactions of V Se with PMS and organic pollutant removal are unclear. Hence, we precisely prepared a series of FeSe 2 @MoO 3 composites with V Se for effective activation of PMS for the removal of various organic pollutants. The roles of V Se are explored via density functional theory (DFT) calculations: (i) regulating the electron distribution of Fe and Mo orbitals in FeSe 2 @MoO 3 for enhancing the PMS adsorption and (ii) promoting the conversion of transition metallic redox pairs (Fe 3+ /Fe 2+ and Mo 6+ /Mo 5+ / Mo 4+ ). The as-prepared FeSe 2 @MoO 3 -8 exhibits excellent catalytic performance via PMS activation in which nearly 100% removal efficiencies of various organic pollutants are achieved within 2−10 min. The quenching experiments, electronic spin resonance (ESR), and probe tests demonstrated that the multiple reactive species like SO 4•− , O 2 •− , • OH, and 1 O 2 contributed to the removal of 2,4-D. Finally, FeSe 2 @MoO 3 -8 was attached to the polyvinylidene difluoride (PVDF) membrane for continuous and efficient removal of 2,4-D, in which the removal efficiency and total organic carbon removal efficiency of 2,4-D were > 90% and >70% within 12 h of operation.

The rapid development of new energy industry is leading to the scarcity of lithium (Li) metal. Rational design of adsorbents for efficient separation of Li+ ion from aqueous media is pivotal to solve the recovery of this valuable resource. Current adsorbents generally suffer from the drawbacks in adsorption capacity, kinetics, and selectivity. Herein, a novel and ultra‐stable metal–organic framework is designed for Li+ separation. The dense oxygen atoms on the cambered wall of its 1D channel encircle to form angstrom‐level tetrahedral ion pockets array, acting as the dominant adsorption sites. This rational distribution of the array avoids the pore blockage caused by the pre‐adsorbed ions, thereby accelerating the diffusion of subsequent ions into the interior pore. Meanwhile, this tetrahedral pocket shows distinct electronegativity and strong chelation effect for Li+. Benefiting from these specifics, this adsorbent exhibits a record‐breaking adsorption capacity for Li+ (76.1 mg g−1) and short equilibrium time (30 min). Moreover, the selective adsorption of Li+ over Na+, K+, Ca2+, and Mg2+ is achieved due to the matched Li+ ion diameter with the pocket/channel sizes and lower energy barrier for dehydration. Thus, this work proposes a feasible strategy for the construction of novel MOFs for ions adsorption.
