Mesoporous single-crystal CoSn(OH)6 hollow structures with multilevel interiors.

ABSTRACT: Hollow nanostructures represent a unique class of functional nanomaterials with many applications. In this work, a one-pot and unusual "pumpkin-carving" protocol is demonstrated for engineering mesoporous single-crystal hollow structures with multilevel interiors. Single-crystal CoSn(OH)6 nanoboxes with uniform size and porous shell are synthesized by fast growth of CoSn(OH)6 nanocubes and kinetically-controlled etching in alkaline medium. Detailed investigation on reaction course suggests that the formation of a passivation layer of Co(III) species around the liquid-solid interface is critical for the unusual hollowing process. With reasonable understanding on the mechanism involved, this approach shows high versatility for the synthesis of CoSn(OH)6 hollow architectures with a higher ord
