Abstract

The fabrication of well-ordered nanoporous graphitic carbon nitride by condensation of cyanamide (CN–NH 2) as a molecular precursor using a colloidal silica crystalline array as a template is described. The resulting sample exhibited a three-dimensionally extended highly ordered pore array as shown by transmission electron microscopy, scanning electron microscopy and nitrogen isotherms. The carbon nitride structure revealed high graphitic nature with C 3N 4 stoichiometry. In particular, the C 3N 4 network structure consists of tri- s-triazine rings (C 6N 7) cross-linked by trigonal N atoms.
