This article investigates the performance of Faradaic electro-swing reactive adsorption (ESA) for CO2 capture using simulations. Traditional methods such as amine scrubbing face energy efficiency challenges, particularly at low concentrations. ESA, which uses electricity regeneration, offers a promising alternative due to its isothermal operation and scalability. The study models ESA quinone-based redox-active carriers in an electrochemical cell with ionic liquid electrolyte, allowing reversible release through voltage control. model estimates system productivity consumption, considering transport chemical kinetics. Key findings show that operating parameters, applied potential gas flow rate, have significant effect on efficiency. Applying −1.3 V improved capacity, reducing time compared −1.1 V. At 1% concentration effective resulted 1.6 kg/(m3·day) consumption 0.6 MWh/tCO2. However, higher rates reduced limitations liquid. Optimization electrode design is essential improve

Electrochemical carbon capture technologies are emerging as sustainable solutions for mitigating CO2 emissions, offering compatibility with renewable energy sources and operation under ambient conditions. However, their development depends on a detailed understanding of the intricate mechanisms driving capture. Conventional characterization methods, which often rely aggregate data or ex situ techniques, fail to real-time, dynamic behavior these systems. This perspective highlights importance in operando techniques uncovering invisible dimensions electrochemical Through case studies spanning molecular, interfacial, system-wide scales, we demonstrate how situ/operando methodologies provide critical insights into reaction mechanisms, interfacial dynamics, device performance. The presented here aim encourage further adoption deepen our underlying ultimately advancement deployment technologies.

The electrochemical and photochemical properties of the rhenium complexes Re(CO)3Cl(phendione) Re(CO)3Cl(AQphen) (phendione = 1,10-phenanthroline-5,6-dione; AQphen naphtho[2,3-h]dipyrido[3,2-a:2',3'-c]phenazine-8,13-dione) were investigated for their potential in CO2 capture. UV-vis spectra dimethyl sulfoxide (DMSO) showed absorption maxima at 370 391 nm, attributed to metal-to-ligand charge transfer (MLCT) transitions, as confirmed by time-dependent density functional theory (TD-DFT) calculations. Electrochemical studies revealed two one-electron reduction events: -0.12 -0.77 V -0.30 -0.79 (vs Ag/AgCl). In presence CO2, second shifted positively 0.20 0.14 V, indicating adduct formation. Association constants (log K) 5.4 3.9 phendione derivatives, respectively. DFT calculations supported formation [quinone-CO2]2- adducts, with bond lengths 1.447 1.406 Å. Under blue LED light (410 nm) experiments spectral changes consistent reduced quinone-CO2 species. These results highlight ability rhenium-quinone engage capture, offering insights into binding behavior.
