From: Localized mass transport channels for electro-upgrade of dilute CO2 toward high-yield C2+ products
a XANES spectra of Cu K-edge. EXAFS spectra of b Cu K-edge and c In K-edge, respectively. d Operando WAXS patterns detected during the activation process. Operando WAXS spectra of e In(OH)3 leaching and f Cu2O generation during the activation step. g 3D images of TOF-SIMS elemental depth distribution of Cu and In elements before and after in-situ activation step. The bottom images are the surface distributions of single atomic In formation. Quasi in-situ NAP-XPS spectra of h Cu LMM and i In 3d spectra during the activation process.
