Key Points

  • The study aims to investigate how spin polarization affects ethanol selectivity during CO2 reduction on CuO surfaces.
  • Conducted a computational study on CuO/Cu to analyze reaction pathways.
  • Examined the effect of magnetic fields on reaction kinetics and selectivity for ethanol and ethylene.
  • Ethanol selectivity increased due to reduced kinetic barriers under magnetic fields.
  • Ethylene selectivity remained less affected as kinetic barriers showed insensitivity under magnetic fields.

Abstract

intermediates on CuO/Cu, providing direct spectroscopic evidence of spin-modulated pathway selection. Computational study suggests that the enhancement of ethanol selectivity is due to the reduced reaction kinetic barrier under MF, while the ethylene selectivity is less affected, mainly due to the insensitivity of the kinetic barriers under MF.
