Hierarchical porous carbon with designed pore architecture and study of its adsorptive properties

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 (>1000m2/g), as it was confirmed by means of electron transmission microscopy and N2 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 C18 and graphitized carbon black GCB.
