Lithium is a strategic element for energy storage. Extraction from surface water promising method the purification of lithium. Synthetic model brines containing lithium and sodium ions were prepared extraction experiments. A hydrophobic deep eutectic solvent (HDES) was synthesized using tetrabutylammonium chloride (TBAC) as hydrogen bond acceptor (HBA) decanoic acid (DA) donor (HBD). Trioctylphosphine oxide (TOPO) chosen coextractant. Fourier transform infrared (FT-IR) 1H NMR analyses confirmed physical interactions between HBD HBA. Response methodology used to optimize operational parameters percentage selectivity. The organic phase TBAC(1)/DA(2) 10 wt % TOPO at T = 23.0 °C pH 10.4 demonstrated highest performance. optimized point yielded selectivity 4.41 an efficiency 48.57% one stage extraction. ion exchange reaction in (DES) by FT-IR spectroscopy. Five regeneration cycles revealed that remained stable after third cycle. brine with same composition Iran's sources 51.63% compared those sodium, potassium, magnesium, calcium ions, which 9.97, 3.11, 4.38, 2.29%, respectively.

In this study, different commercial microfibrous fabric cloths were efficiently functionalized with polyethylenimine (PEI) and optimized respect to amine loading for adsorptive removal of CO2 from flue gas. The synthesized adsorbents characterized by various techniques such as field emission scanning electron microscopy (FESEM), atomic force (AFM), Fourier transform infrared (FTIR) analysis, tensile properties the fabrics. adsorption capacities amine-functionalized sorbents measured using a thermogravimetric analyzer. It was found that an optimal PEI 60 wt % on polyester-based cloth (PEFC) resulted in highest capacity fastest kinetics while studying effects partial pressures (in range 5–100 kPa) performance under atmospheric pressure. equilibrium PEI-loaded PEFC at 75 °C 1.60 1.93 mmol CO2/g 10% CO2/N2 gas mixture pure CO2, respectively. multicycle temperature swing adsorption/desorption also investigated simulated both dry humid conditions, it observed working uptake after 15 cycles 1.07 1.15 sorbents.

Hierarchically Porous Heteroatom‐co‐Doped Carbons for Enhanced Carbon Dioxide Capture

Energy & environment materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 22, 2025

The efficiency of carbon dioxide (CO 2 ) adsorption in carbonaceous materials is primarily influenced by their microporosity and thermodynamic affinity for CO . However, achieving optimal heteroatom doping precise micropore engineering through advanced activation techniques remains a significant challenge. We introduce solvent‐free one‐pot method using polythiophene, melamine, KOH to prepare highly microporous, heteroatom‐ co ‐doped carbons (NSC). This approach leverages sulfur from nitrogen the agent enhance capture performance. Our results demonstrate that optimized sample, NSC‐800, achieves capacity 280.5 mg g −1 at 273 K 1 bar, attributed its high (6.5 at.%) (3.4 contents, specific surface area 2888 m , volume 1.685 cm 3 moderate isosteric heat (27.7 kJ mol indicates physisorption‐driven mechanism, as confirmed close alignment with pseudo‐first‐order polynomial model ( R > 0.99) across temperatures 303–323 K. study reveals NSC‐800 also displays efficient regeneration after ten cycles adsorption–desorption under flue gas conditions (15% 85% N 313 K), highlighting potential regenerable, energy‐efficient adsorbent practical applications.
