Zeolites are a class of inorganic materials composed of SiO2 and Al2O3 (aluminosilicates) with alkali metals as countercations. They exhibit high surface areas with highly ordered micropores and are widely used in catalysts. The catalytic ability and structural regularity of zeolites are enticing features for their use as templates in synthesizing nanostructured carbon materials. In 2000, Kyotani and co-workers reported the synthesis of zeolite-templated carbon (ZTC) using Y zeolite (faujasite, FAU) as the template material. The studies used Y zeolite with a porous diamond-like framework of spherical cavities (supercage, ~1.3 nm in diameter): ZTC was prepared by transcription of the structural information of zeolite. A composite of furfuryl alcohol and Y zeolite powder was heated, followed by treatment with propylene at 600-800 °C for CVD to achieve the ordered porous structure of single-walled nanographene derivatives. Thermal annealing at 900 °C for 3 h ensures a more robust 3D structure. After CVD, the resulting material was washed with HF and HCl solutions to obtain the ZTCs. This procedure allowed the ZTC to retain the highly ordered microstructure of the zeolite with carbon architecture.
