Abstract

Zeolite-templated carbons (ZTCs) are ordered microporous carbons synthesized by using zeolite as a sacrificial template. Unlike well-known ordered mesoporosu carbons obtained by using mesoporous silica templates, ZTCs are consisting of curved and single-layer graphene frameworks, thereby affording uniform micropore size (ca. 1.2 nm), developed microporosity (~1.7 cm3 g–1), very high surface areas (~4000 m2 g–1), good compatibility with chemical modification, and remarkable softness/elasticity. Thus, ZTCs have been applied to many applications such as hydrogen storage, methane storage, CO2 capture, liquid-phase adsorption, catalysts, electrochemical capacitors, batteries, and fuel cells. Herein, the relevant researches are summarized, and the properties as well as the performances of ZTCs are compared with those of other materials including metal-organic frameworks, to elucidate the intrinsic advantages of ZTCs and their future development.
