Publication number: 20240360576Abstract: 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 ?max 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, (?max 63%) at an overpotential of 890 mV (?1.4 V vs Ag/AgCl); acetic acid with ?max 18% at an overpotential of 390 mV (?1.0 V vs Ag/AgCl); and acetone with ?max 10% at an overpotential of 620 mV (?1.2 V).Type: ApplicationFiled: April 29, 2024Publication date: October 31, 2024Applicant: The Trustees of Princeton UniversityInventors: Andrew B.
