This study provides compelling experimental evidence of the synergistic effects reaction pressure, oxidation state, and catalyst morphology on C2+ selectivity copper (Cu) oxide catalysts in electrochemical CO2 reduction (ECR). We employed femtosecond laser structuring thermal treatments to synthesize Cu(0), Cu(i), Cu(ii), a mixed state Cu(x) with characteristic micro- nano-morphologies. The optimal pressure for maximizing productivity aqueous bicarbonate media was established by assessing products at different imposed pressures custom-designed, pressurizable two-compartment cell. Among thermally produced Cu(i) only unstructured exhibiting ethylene gas-phase selectivity. Nanostructuring enhanced such that all three states could produce ethylene. More importantly, nanostructured comprising well-dispersed exhibited as well ethane production - associated undercoordinated Cu stabilizing intermediates facilitating charge transfer yield longer products. work important insights into key factors influencing Cu-based catalysts, establishing basis an informed design high-energy density

A new method based on binary mixture concept for prediction of ionic liquids critical properties using molecular dynamics simulation

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 4, 2025

All substances exhibit complex behavior near their critical points, where even slight variations in temperature and pressure can lead to significant changes density, heat capacity, compressibility. This rapid variation results a loss of surface energy maximizes the compressibility capacity fluids at point. study employed molecular dynamics (MD) simulations based on binary mixture concept predict properties ionic liquids (ILs) that are difficult measure experimentally. Initially, validate this method, we investigated density pure water, ethanol, across different temperatures pressures, specifically phase transition, critical, supercritical points. Then, these were studied for [C4mim][BF4] IL its The water-ethanol compared with experimental data. simulation revealed points resembles three middle point represents mixture's predicted 1400 ± 10 K 11 0.5 bar, respectively.
