Organic magnetic nanoparticles catalyze CO2 capture in hydrogen-bonded nanocages via water-driven crystallization

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Апрель 18, 2025

Abstract Limiting global warming increasingly relies on the development of environmentally friendly CO 2 capture strategies. Crystallization is renowned for versatile separation and purification, yet traditional compound crystallization-based still necessitates intricate preparation processes, stringent reaction conditions, high regenerative energy consumption. As an ambitious sustainability goal, natural water could be used as a precursor crystallization to construct hydrogen-bonded cages capture, but main obstacles are slow kinetics low capacity. Here, water-activation-induced strategy by organic magnetic nanoparticles (Methionine@Fe 3 O 4 ) has been proposed efficient capture. Local ordering strengthened hydrophobic amino acids abundant nucleation sites provided create hotspots hydration phase transition crystal growth, with capacity 118.7 v/v (22.7 wt%). Favorable biocompatibility stable performance conducive industrial application this nanomaterial, excellent recyclable property enables simple from clean water. This demonstrates extraordinary potential compared state-of-the-art systems, thus providing inspiration sustainable storage zero resource depletion (ZRD).

Molecular Insights into the Concentration Dependent Promotion Effect of Tetrabutylammonium Bromide on Hydrate Growth: A Molecular Dynamics Simulation Study

Langmuir, Год журнала: 2024, Номер 40(49), С. 26283 - 26291

Опубликована: Ноя. 21, 2024

Tetrabutylammonium bromide (TBAB) has been proven to improve the growth of hydrate via experimental methods, which may be attributed its different concentrations. In this study, molecular dynamics (MD) simulation is employed investigate concentration dependent promotion effect TBAB on CO2 hydrate. The tetrahedral order parameter, number cages, crystal trajectories, significant microconfigurations, and distribution are analyzed in detail. It found that more prominent at low concentrations (5 10 wt %) than high (15 20 %). During crystal, tetrabutylammonium (TBA+) ions adsorb serve as guest molecules form TBA+ semiclathrate cages. Then, cages undergo a self-adjustment process induce generation At concentrations, great accumulation hydrate–liquid interface disturbs effective adsorption processes, tightly packed arrangement gas–liquid partially inhibits mass transfer CO2. This study provides visible mechanisms from microscopic level, complements vacancy studies.
