Advanced Materials for NH3 Capture: Interaction Sites and Transport Pathways

Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 16(1)

Published: June 27, 2024

Abstract Ammonia (NH 3 ) is a carbon-free, hydrogen-rich chemical related to global food safety, clean energy, and environmental protection. As an essential technology for meeting the requirements raised by such issues, NH capture has been intensively explored researchers in both fundamental applied fields. The four typical methods used are (1) solvent absorption ionic liquids their derivatives, (2) adsorption porous solids, (3) ab-adsorption liquids, (4) membrane separation. Rooted development of advanced materials capture, we conducted coherent review design different materials, mainly past 5 years, interactions with molecules construction transport pathways, as well structure–property relationship, specific examples discussed. Finally, challenges current research future worthwhile directions proposed.

Rational design of deep eutectic solvents with low viscosities and multiple active sites for efficient recognition and selective capture of NH₃

Smart Molecules, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 5, 2025

Abstract Efficient recognition and selective capture of NH 3 is not only beneficial for increasing the productivity synthetic industry but also reducing air pollution. For this purpose, a group deep eutectic solvents (DESs) consisting glycolic acid (GA) phenol (PhOH) with low viscosities multiple active sites was rationally designed in work. Experimental results show that GA + PhOH DESs display extremely fast absorption rates (within 51 s equilibrium) high solubility. At 313.2 K, capacities (1:1) reach 6.75 mol/kg (at 10.7 kPa) 14.72 201.0 kPa). The solubility at pressures were minimally changed after more than 100 days exposure. In addition, remain highly stable 10 consecutive absorption‐desorption cycles. More importantly, can be selectively captured by from /CO 2 /N /H mixtures. 1 H‐NMR, Fourier transform infrared theoretical calculations performed to reveal intrinsic mechanism efficient DESs.

NH₃ Uptake and NH₃/CO₂ Separation by a [MEA][SCN]-Based Deep Eutectic Solvent: Experimental Investigation and Process Simulation

Energy & Fuels, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

NH3 has attracted increasing attention as a fundamental material and promising hydrogen carrier. The uptake of from NH3-containing exhausted gas presents economic environmental issues. In this study, [MEA][SCN] was paired with glycerol, acetamide, formamide, phenol (PhOH), ethylene glycol, urea, glycerolformal, or 1,3-dimethyl-2-imidazolidinone to construct deep eutectic solvents (DESs) for effective absorption NH3/CO2 separation investigation. All the [MEA][SCN]-based DESs exhibited good performance. Notably, [MEA][SCN]-PhOH (1:1) realized an atmospheric capacity 0.2459 g NH3·g–1 DES selectivity 194.53 at 303.15 K. Based on experimental data, new process recovery melamine tail using (DES-M) developed simulated operational parameters optimization, heat exchange network design, evaluation. DES-M can recycle purity 99.6% save 82.01% utility costs compared water scrubbing method. integration design in reduces 66.94% low-pressure steam 9.00% costs. Specially, optimized exceed 59% after-tax rate return renewable energy.
