The intercalation of sugar in smectite clays and the resulting clay−carbon composites after thermal treatment Ar are described. Sugar activation by H2SO4 affords novel which layer structure clay is preserved. Combined XRD TEM measurements strongly suggest that carbonization at 600 °C leads to graphenes distributed over surfaces, forming a nanometric carbonaceous film. Thermal analysis results show enhanced stability with mineral preserving its layered even 900 °C. Acid demineralization substrate yields materials high surface areas. templating role growth revealed HRTEM micrographs, limited packing accompanied improved present low-temperature-synthesized absorbents without need high-temperature activation.
