Ordered mesoporous carbon nanoparticles have been synthesized by a nanocasting procedure from furfuryl alcohol impregnation into alumino-silica UVM-7 material. By a proper adjustment of the synthesis parameters, furfuryl alcohol volume vs. template pore volume, it was possible to obtain a carbonaceous templated material which keeps the hierarchical bimodal porosity of the silica together with its high surface area (>1000 m(2)/g), as it was confirmed by means of electron transmission microscopy and N(2) adsorption isotherms. This carbon material was evaluated by testing it as a sorbent for several pesticides in aqueous solutions. Its absorption efficiency was compared with typical commercial solid phase extraction materials such as Silica C(18) and graphitized carbon black GCB. (C) 2009 Elsevier Masson SAS.
