Solution-phase synthesis of inorganic hollow structures by templating strategies

This paper presents a concise review of the solution-phase synthesis of hollow micro- and nanostructures by using suitable templates such as hard templates, soft templates and reactive templates. Non-spherical hollow structures such as single-walled (a) and double-walled (b) Ag rhombododecahedral cages can be fabricated through the microscale Kirkendall Effect via reactive templates.
