Preparation of SnO₂ hollow nanospheres by a solvothermal method

Excerpt

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 [1]. 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 [2‐6]. 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 [7‐9], 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. …
