Porous carbon materials or activated carbons are characterized by their highly developed internal surface area and porosity. Especially the development of micro- and mesopore is of great importance. Many novel approaches to control such pore structure have been proposed. Among them, one of the most important and elegant techniques is the template carbonization method. So far many researchers have prepared novel porous carbons with the template technique using a variety of inorganic porous templates, such as layered clay, porous glass, silica gel, silica sol, zeolite and mesoporous silica. In this review, we introduce such template-mediated approach and highlight how useful and versatile the template technique is for the production of porous carbons.
