Summary: A series of metal-organic framework (MOF)-supported flexible, self-adaptive dual-metal-site pairs (DMSPs) were screened as potential electrocatalysts for CO2 reduction reaction (CO2RR) using density functional theory calculations. Among them, MOF-808-EDTA-FeFe and MOF-808-EDTA-FePt were identified as promising CO2RR electrocatalysts towards C1 and C2 products. This study not only provides potential candidates for highly selective CO2RR electrocatalysts leading to C1 and C2 products but also offers mechanistic insights into the dynamic nature of DMSPs for stabilizing various reaction intermediates in the CO2RR process.

Summary: In this study, Zirconium-based MOF and chitosan composites were synthesized as efficient adsorbents for removing Cr(VI) ions from aqueous solution. The structure and morphology of MOF-808/chitosan were characterized, and the adsorption process was found to follow pseudo-second-order kinetic model and Langmuir isotherm model. Thermodynamic investigation indicated that the adsorption process was spontaneous, disordered, and endothermic. The DFT study confirmed the role of hydrogen bonding and electrostatic attraction in the adsorption process.

Summary: Al-NDC@GO composites were successfully prepared via the reaction of 1,4-naphthalene dicarboxylic acid (1,4-H2NDC), Al(NO3)(3)center dot 9H(2)O, and graphene oxide (GO) in water. The composites exhibited remarkable adsorption capacity for pyridine, quinoline, and indole in the liquid phase, high adsorptive selectivity in the presence of naphthalene and benzene, and satisfactory recyclability. The excellent adsorption performance of the composites is attributed to the high surface area, porosity, and the presence of unsaturated metal sites and excessive oxygen groups on exfoliated layers of GO sheets.

Summary: It is crucial to develop a sustained-release pralidoxime chloride (2-PAM) drug system that can target the brain for the treatment of neurotoxicant poisoning. In this study, thiamine (VB1) was incorporated onto the surface of MIL-101-NH2(Fe) nanoparticles, which can bind to the thiamine transporter on the blood-brain barrier. Pralidoxime chloride was loaded within the composite, resulting in a composite drug (2-PAM@VB1-MIL-101-NH2(Fe)) with a loading capacity of 14.8% (wt). The composite drug showed a pH-dependent drug release rate, with a maximum release rate of 77.5% at pH 4. Furthermore, the composite drug exhibited sustained release and stable reactivation of poisoned acetylcholinesterase (AChE) in mice, with a reactivation rate of 42.7% in ocular blood samples at 72 h. Cross-blood-brain-barrier penetration and AChE activity restoration in the brain of poisoned mice were observed with the composite drug. It is anticipated that this composite drug can serve as a stable therapeutic option with brain targeting and prolonged drug release properties for nerve agent intoxication in the middle and late stages of treatment.
