Abstract:The well-known physical phenomenon Ostwald ripening in crystal growth has been widely
employed in template-free fabrication of hollow inorganic nanostructures in recent years.Nevertheless,all
reported works so far are limited only to stoichiometric phase-pure solids.In this work we describe the first
investigation of doped (nonstoichiometric) materials using Ostwald ripening as a means of creating interior
space.In particular,we chose the xSnO2 (1 x)TiO2 binary system to establish preparative principles for
this approach in synthesis of structurally and compositionally complex nanomaterials.In this study,uniform
Sn-doped TiO2 nanospheres with hollow interiors in 100% morphological yield have been prepared with
an aqueous inorganic route under hydrothermal conditions.Furthermore,our structural and surface analyses
indicate that Sn4 ions can be introduced linearly into TiO2,and preferred structural phase(s) can also be
attained (e.g.,either anatase or rutile,or their mixtures).Fluoride anions of starting reagents are adsorbed
on the surface sites of oxygen.The resultant anion overlayer may contribute to stabilization of surface and
creation of repulsive interaction among the freestanding nanospheres.On the basis of these findings,we
demonstrate that Ostwald ripening can now be employed as a general hollowing approach to architect
interior spaces for both simple and complex nanostructures.
Introduction
In recent years,synthetic fabrication of discrete inorganic
nanostructures with an interior space has aroused significant
attention.
1 12 This type of chemical approach normally makes
use of various templating methodologies.For example,micelles
and vesicles,sol gel networks,colloidal polymeric and silica
beads,sacrificial metal templates,and even gas bubbles,etc.,
have been utilized.
3 12 Apart from templating synthesis,recent
development in the field is also directed to template-free
processes.In particular,various known physical phenomena,
such as oriented attachment,
13 15 Ostwald ripening,
16 and
Kirkendall effect,
17 19 have been employed in many wet
fabrications of hollow inorganic nanostructures.

them,mass transport via Ostwald ripening has been proven to
be a facile approach to generate symmetric and/or asymmetric
interior spaces,including core shell spaces and multiple shell
