From: One-dimensional single atom arrays on ferroelectric nanosheets for enhanced CO2 photoreduction
a, b HAADF-STEM images of BTOAu3. c, d HAADF-STEM images of BTOPAu (enlarged area from a and b). Line scan HAADF intensity profile of e site A (direction-1 and 2) and f array A (direction-1 and 2) versus distance. g, h Multiple HAADF-STEM images of (b) BTOAu3 and (d) BTOPAu. i Au L3-edge normalized XANES spectra and j Au L3-edge EXAFS spectra in R space of BTOAu3, BTOPAu, and references. k Fitting results of the k2-weighted FT spectrum of BTOPAu at the Au L3-edge.
