Preparation of SnO2 hollow nanospheres by a solvothermal method

During the past decade, considerable efforts have been made to fabricate inorganic materials with hollow nano/micro structures because many interesting optical, electronic, magnetic, catalytic and chemical properties are associated with these structures . Among the methods that have been used for the synthesis of hollow nano/micro structures, hard- and soft-template syntheses are the two mostly used routes [2, 3, 4, 5, 6]. The size and morphology of the product can be controlled very well through choosing appropriate template, however, the removal of template is a rather complex process. Recently, a new sacrificial-template route is used to synthesis nanomaterials [7, 8, 9], in which the template materials act as one reactant and will be used up after the reaction, hence, the step for the template removal is successfully leaving out.
SnO2 is a wide-band-gap semiconductor (Eg ≈ 3.62 eV, at room temperature) and a well-known material having applications in transparent electrodes ,...
