Fig. 2

a Top (i) and (ii) cross-sectional view SEM images of monolithic ZIF-8-NH2 support. b TEM image of AgSA+NP/ZIF. Inset is the statistical size distribution of Ag nanoparticles. c AC-HAAD-STEM image of AgSA+NP/ZIF (the bright dots in the red circles are Ag single atoms). Inset is the HAAD-STEM image of AgSA+NP/ZIF. d HAADF-STEM with elemental mapping images of AgSA+NP/ZIF. e Fourier-transformed EXAFS results of AgSA/ZIF, AgNP/ZIF, AgSA+NP/ZIF, Ag foil and Ag2O at the Ag K-edge. f EXAFS fitting curve of AgSA+NP/ZIF in R space.
