Rational design and fabrication of metal–organic framework-derived metal oxide (MO) materials featuring a hollow structure active support can significantly enhance their catalytic activity for specific reactions. Herein, series Co3O4 nanoparticles (NPs) immobilized in boron nitride (denoted as Co3O4@BN) with highly open precisely controllable structures were constructed by an situ self-assembly method combined controlled annealing process. The obtained Co3O4@BN not only possesses but also shows dispersed NPs high loadings up to 34.3 wt %. Owing the ultrafine particle size dispersity, optimized exhibits cycloaddition CO2 epoxides under mild conditions (i.e., 100 °C balloon), resulting at least 4.5 times higher yields (99%) styrene carbonate than that synthesized pristine ZIF-67. This strategy sheds light on rational MO various advanced applications.

Uranium Extraction from Seawater: A Novel Approach Using Aluminum Fumarate‐based Metal‐Organic Framework Aerogels

Chemistry - An Asian Journal, Год журнала: 2025, Номер unknown

Опубликована: Фев. 11, 2025

Abstract Efficient extraction of uranyl ions from seawater is crucial for the commercialization nuclear technology. Metal‐organic frameworks (MOFs), with their superior uranium properties, face challenges in large‐scale applications due to powdery nature and difficulty assembling them into mechanically stable macroscopic composites. To address this, successfully synthesized 90 wt % nanoMOF (aluminum fumarate) loaded directional aerogels (AlFA‐3‐10) using polyvinyl alcohol (PVA) as an adhesive, which demonstrates robust strength longitudinally transversely. Our adsorption experiments reveal that at a pH 8 (akin seawater), AlFA‐3‐10 achieves maximum capacity 1146.25 mg g −1 , maintaining this exceptional performance over five cycles. Notably, simulated seawater, exhibits high selectivity minimal interference other ions. The pores within facilitate fluid transmission exchange, ensuring optimal contact between MOF ions, thereby enhancing electrostatic attraction electron transport improved capture efficiency. This streamlined approach maximizes intrinsic potential nano‐MOFs heralds new era integration composite materials.
