Templated Porous Carbon Materials Recent Developments... 

Several reviews covering the synthesis, properties and applications of porous carbons, especially mesoporous carbon materials, can be found in the literature. In this chapter, we summarise the recent developments in the synthesis and characterisation of templated porous carbon materials. Particular attention is paid to the synthesis of structurally ordered porous carbon materials with narrow pore size distribution via both hard and soft template methods. We especially emphasise those so-called breakthroughs in the preparation of porous carbon materials. The chapter is divided into three sections according to the pore size of carbon materials we first consider the synthesis of microporous carbon materials using zeolites and clays as hard template, then summarise the preparation of mesoporous carbon materials via both hard template and self-assembly...

The surface chemistry of a carbon is known to play a crucial role in many applications, most notably in adsorption and catalysis [91-94]. It has been observed that the surface of templated porous carbons mainly has oxygen-containing functional groups, such as carboxyl, carbonyl, quinone, and hydroxyl [76,94,95]. Such groups, especially the carboxyls, can be eliminated by high-temperature...

These porous carbons, referred to as MgO-templated carbons, have been applied in various areas such as electrodes for electric double-layer capacitors [88], as absorbents for gasoline, and as anodes for lithium ion batteries. The application of these MgO-templated porous carbons has been reviewed elsewhere in Japanese [89].
