Graphitic carbon nitride was synthesized in layered aluminosilicates via solid state reaction. At first, metal-urea complexes such as magnesium chloride-urea and iron(III) nitrate-urea, eutatic solution, were intercalated into layered aluminosilicates via solid state reaction at 105 oC for 3 hours. According to X-ray diffraction analysis, the basal spacing of metal-urea / layered aluminosilicates was expanded to 1.76 nm compared to one of Na+ intercalated layered aluminosilicates, 0.96 nm, indicating that metal urea complex was successfully intercalated into layered aluminosilicates. By calcining the prepared metal-urea/layered aluminosilicates nanohybrid at 500 oC for 3 hours, urea in the interlayer of layered aluminosilicates was polymerized to form graphitic carbon nitride. UV-visible spectrum shows that the calcined sample has an absorption edge at around 450 nm, thus making the nanohybrid pale-yellow, which is similar to one of bulk graphitic carbon nitride.
