TEM image and SAED pattern of pure WO3 and Ag(60nm)@(2D-WO3) CSNS.

(a), Ag(60nm)@(2D-WO3) CSNS with the core and the shell clearly resolved. The upper right inset is HRTEM image of Ag(60nm)@(2D-WO3) CSNS showing clearly resolved layered structure and the lower right inset shows the fringe spacing of 0.37 nm indexed to the (200) planes. (b), SAED pattern of the Ag(60nm) core can be indexed to standard Ag FCC crystal structure. (c), SAED pattern of the WO3 shell assigned to monoclinic structure.
