“…A soft template based on the NH 3 bubbles was proposed for the synthesis of the hollow core-shell ZnSn(OH) 6 microcrystals, as shown in Scheme 1. 13,14 However, the crystal morphology depends not only on the intrinsic crystal structure but also on the synthesis conditions. Then, ZnSn(OH) 6 nanoparticles continue to aggregate around the surface of NH 3 bubbles, driven by the minimization of interfacial energy.…”

“…4 ZnSnO 3 and ZnSn(OH) 6 microcube films were obtained by hydrothermal method on zinc oxide-seeded indium tin oxide substrates. 13 ZnSn(OH) 6 micro-and nanocubes were grown on pure tin substrates via a seedless hydrothermal synthesis method. 14 Till now, it has been a great challenge to control the synthesis of ZnSn(OH) 6 crystals with special morphology.…”

In this study, a room temperature NH 3 bubble templating technique is developed to prepare zinc hydroxystannate [ZnSn(OH) 6 ] hollow core-shell microspheres. Then, via a hydrothermal recrystallizing process, ZnSn(OH) 6 hollow core-shell microcrystals with polyhedral morphology can be successfully obtained. It was found that the concentration of NH 4 F plays a crucial role in the morphology of the product. The optimal condition for the formation of hollow core-shell ZnSn(OH) 6 microcrystals is that the concentration of NH 4 F is at 0.25 mol L À1 while the concentration of NaOH is fixed at 0.25 mol L À1 . Reaction time has also a great influence on the morphology of the product. With the reaction time prolonged, hollow core-shell ZnSn(OH) 6 microspheres would gradually crystallize into hollow coreshell ZnSn(OH) 6 polyhedral microcrystals. The samples have been characterized by means of X-ray power diffraction (XRD), field emission scanning electron microscopy (FESEM), X-ray photoelectron spectra (XPS), selected area electron diffraction (SAED) and transmission electron microscopy (TEM). The formation mechanism of the ZnSn(OH) 6 hollow core-shell microcrystals with polyhedral morphology has been discussed based on the experimental results.

Micro/nanostructured ZnSn(OH) 6 /ZnO composite architectures were synthesized through a simple one-step hydrothermal method. Phase structure and morphology of the products were characterized by using X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). ZnSn(OH) 6 microcubes and ZnO nanorods with uniform size were interconnected to form the micro/nanostructured architectures. ZnO nanorods preferentially grow at edges and corners of the microcubes. Morphology of the products was susceptible to concentration of the reactants. With increasing reactant concentration, the ZnO nanorods grown on the surfaces of ZnSn(OH) 6 microcubes disappeared. Meanwhile, the smooth surfaces of the ZnSn(OH) 6 microcubes become coarsened and were etched to spherical outlines. Growth mechanism of the micro/nanostructured ZnSn(OH) 6 /ZnO composite architectures was discussed and thermal decomposition properties of the micro/nanostructured ZnSn(OH) 6 /ZnO composite architectures at high temperature were examined.
