Abstract Ordered mesoporous carbon/silica hybrid materials were synthesized using the oligomer of urea-formaldehyde resin as carbon source, triple copolymer surfactant F127 as template and tetraethyl-orthosilicate (TEOS) as silica source via evaporation induced self-assembly (EISA)method. Through changing carbonization temperature, mesoporous carbon/silica hybrid samples with different BET surface areas and pore size distributions were obtained. The materials were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Thermo Gravimetric Analyzer (TGA) and nitrogen adsorption-desorption analysis. The results showed that carbonization temperature would directly influence the pore structure. When the carbonization temperature is 850℃, the mesoporous carbon/silica hybrid material with perfect orderliness and narrow pore size distribution can be prepared.
