The application of existing ternary betaine (Be)-based deep eutectic solvents (DESs) faces inevitable limitations due to the low regenerability and water absorption capability DESs. In this study, three Be-based DESs with different molar ratios were prepared by adding promoter diethanolamine (DEA) binary system Be ethylene glycol (EG). effects DEA, temperature, flow rate on CO2 then investigated. At a ratio 1:5:8 (Be:EG:DEA), capacity reached 0.207 g CO2/g DES at an temperature 30 °C gas 50 mL/min. addition contents triggered dissolution, forming + system. added inhibited Evaluation showed that their capacities remained above 0.176 after five cycles absorption–desorption.

Abstract Improving the kinetics and selectivity of CO 2 /CO electroreduction to valuable multi-carbon products is a challenge for science requirement practical relevance. Here we develop thiol-modified surface ligand strategy that promotes electrochemical CO-to-acetate. We explore picture wherein nucleophilic interaction between lone pairs sulfur empty orbitals reaction intermediates contributes making acetate pathway more energetically accessible. Density functional theory calculations Raman spectroscopy suggest mechanism where increases sp hybridization (ad) , facilitating rate-determining step, CO* (CHO)*. find ligands stabilize (HOOC–CH )* intermediate, key intermediate in pathway. In-situ shows shifts C–O, Cu–C, C–S vibrational frequencies agree with ligand-intermediate interactions. A Faradaic efficiency 70% obtained on optimized thiol-capped Cu catalysts, onset potentials 100 mV lower than case reference catalysts.

The strong binding energy of CO on iron surfaces has rendered Fe electrodes as poor electrochemical 2 reduction (eCO2R) catalysts, predominantly producing hydrogen. Recent studies tuning the microenvironment near catalyst by local electric field in nonaqueous environments have been shown to promote eCO2R facilitating activation step. Herein, use tetraethylammonium (TEA) cation tune surfaces, such that it leads formation industrially relevant oxalates (C products), is reported. At optimal concentrations, developed system achieves 25 mA cm −2 current density and Faradaic Efficiencies up 75% toward oxalate. Furthermore, situ attenuated total reflectance Fourier transform infrared spectroscopy indicates presence surface‐adsorbed TEA cations other species leading well‐known outer‐sphere mechanism electron transfer during eCO2R. employment Fe, along with tuning, not only demonstrates high catalytic performance but also provides a safer more sustainable alternative toxic catalysts Pb dominate eCO R literature. These findings pave way for further optimization scale‐up process, offering viable route chemical production mitigation.
