Abstract

In this paper, a review on the synthesis methods of carbon hollow micro/nano structures according to the recent literatures is presented. At first, the kinds of hollow structures will be mentioned and then, the synthesis methods of carbon hollow spheres (CHS) including chlorination of metallcarbides, hard templating, soft templating and self templating will be discussed. Two first methods are widely used for synthesis of CHS. Hereby, in the first step, basic concepts of the methods and then, kinds of templates used in synthesis of CHS and the related publications will be considered. Soft and self templating methods are the most important ways for synthesis of hollow structures based on polymer, metal oxides and silica materials. These methods are not appropriate for the synthesis of CHS due to hydrothermal and carbonization processes at high temperature. Consequently, these methods will be briefly described.
