摘要:
In the present study the intestine-like binary SnO2/TiO2 hollow nanostructures are one-pot synthesized in aqueous phase at room temperature via a colloid seeded deposition process in which the intestine-like hollow SnO2 spheres and Ti(SO4)(2) are used as colloid seeds and Ti-source, respectively. The novel core (SnO2 hollow sphere)-shell (TiO2) nanostructures possess a large surface area of 122 m(2)/g (calcined at 350 degrees C) and a high exposure of TiO2 surface. The structural change of TiO2 shell at different temperatures was investigated by means of X-ray diffraction and Raman spectroscopy. It was observed that the rutile TiO2 could form even at room temperature due to the presence of SnO2 core and the unique core-shell interaction. (C) 2009 Elsevier B.V. All rights reserved.
