摘要： Disclosed is a technique for reducing CO2 to oxalate utilizing a copper-free, nickel-enhanced electrocatalyst (such as a nickel-enhanced (Cr2O3)3(Ga2O3) electrocatalyst) that can be used for producing, e.g., 1-butanol, in exceedingly high yields. Disclosed herein are various synthetic methodologies for introducing nickel into the electrocatalysts, and described is the characterization, and optimization of the Ni enhanced electrocatalysts for the reduction of CO2 to 1-butanol with a maximum faradaic efficiency ξmax of 64%, at an overpotential of 900 mV (−1.48 V vs Ag/AgCl), and having an onset overpotential of 320 mV. The product selectivity is potential dependent with other C2+ products such as 3-hydroxybutanal, (ξmax 63%) at an overpotential of 890 mV (−1.4 V vs Ag/AgCl); acetic acid with ξmax 18% at an overpotential of 390 mV (−1.0 V vs Ag/AgCl); and acetone with ξmax 10% at an overpotential of 620 mV (−1.2 V).

摘要： An embodiment of the disclosure provides an electrochemical catalyst composite and a method of producing the same. The electrochemical catalyst composite according to an embodiment of the disclosure is a hybrid material having a heterojunction structure between metal phosphide with controlled crystal strain and the MXene, in which metal phosphide produced by a synergy effect between the two materials prevents an overlapping phenomenon caused by the van der Waals force of the two-dimensional MXene material and increases a surface area, thereby having an effect on increasing reaction active points. Further, metal phosphide material with the controlled strain causes an electron structure of an element in the MXene support to be rearranged, thereby inducing change in an electrical structure. In addition, the MXene support combined with metal phosphide having the controlled strain promotes a hydrogen generation reaction, thereby having effects on enhancing the electrochemical performance and improving the electrical properties and stability of the material.

摘要： A method of electrochemical reduction of CO2 includes the use of a catalyst of Cu/Cu2O particles including Cu/Cu2O interfaces. The catalyst may be included in an electrochemical cell for the conversion of CO2 to value-added products. The electrochemical cell may include an anode, a cathode including the Cu/Cu2O particles including Cu/Cu2O interfaces, and an aqueous medium containing CO2 or CO3−2. The CO2 or CO3−2 is reduced by contacting the Cu/Cu2O particles with the aqueous medium while supplying electricity to the cell. The conversion of CO2 by the electrochemical reduction thereof has higher Faradaic Efficiency due to the Cu/Cu2O interfaces in the Cu/Cu2O particles.

摘要： An electrochemical process, and related method and system to upgrade captured CO2 into value-added products. CO2 capture technologies based on chemisorption present the potential to lower net emissions of CO2 into the atmosphere. The use of alkali cations to tailor the electrochemical double layer allows achieving the valorization of chemisorbed CO2 in an aqueous amine-based electrolyte, by placing the CO2 of the amine-CO2 adduct sufficiently close to the site of an heterogeneous reaction at the working electrode. It is revealed, using electrochemical studies and in-situ surface-enhanced Raman spectroscopy, that a smaller double layer distance can correlate with improved activity for CO2 to CO from amine solutions.
