a–c HAADF-STEM images in low magnification of Au1 (a), Au1&n (b), and Aun (c) catalyst. d–f Aberration-corrected HAADF-STEM images in high magnification of Au1 (d), Au1&n (e), and Aun (f) catalyst. g, XPS Au 4 f spectra of Au/S-1 catalysts with different loadings. h, i In-situ SR-FTIR spectra of C3H6 adsorption (h) and that in the range of 2800-3100 cm−1 (i) of the Au1 and Aun catalyst at 40 oC. The Au loadings for the Au1, Au1&n, and Aun catalysts are 0.004, 0.014, and 0.026 wt%, respectively.
