Morphology and composition characterization.
(a, b) FESEM images and (c–e) TEM images of CoSn(OH)6 nanoboxes; (f) a nanobox with well-developed interior; (g) a TEM image showing the shell structure of a nanobox, on which a very thin layer of Co (III) species is covered on the outer surface; (h) SAED pattern of a single nanobox; (i) HRTEM image along a zone axis of <001>; (j) elemental mapping showing the homogenous dispersion of Sn, Co and O element in CoSn(OH)6 nanoboxes.
