Fig. S1 TEM images of sample 1 (a), sample 2 (b, c) and sample 3 (d). The images
indicated that the size of silver nanoparticles could be well controlled by changing the
silver ion exchange degree of the samples.

Fig. S2 Electron dispersive spectrum (EDS) analyses of sample 1 (a), sample 2 (b) and
sample 3 (c) before electrochemical reduction, and electron diffraction (ED) analysis of
sample 2 (probably containing some diffraction of zeolite-FAU). The EDS results
indicate that these samples possess different ion exchange degree from the Ag/Al and
Na/Al ratios, as shown in table 1, and ED analysis indicates that the silver nanoparticles
might be polycrystals.
