From: Active and conductive layer stacked superlattices for highly selective CO2 electroreduction
a Bi L3-edge XANES and b corresponding FT-EXAFS spectra of BiCuSeO after CO2RR. c Cu K-edge XANES spectra and d corresponding FT-EXAFS spectra of BiCuSeO after CO2RR. Wavelet transform of the k2-weighted EXAFS data of e Bi L3-edge and f Cu K-edge.
