SiO2-TiO2 pillared layered manganese oxide nanohybrid was successfully synthesized by preliminarily expanding the interlayer of H-type layered manganese oxide using dodecylamine, followed by reacting it with a mixture solution of titanium isopropoxide and tetraethylorthosificate. The basal spacing and the pillared agent content of the obtained materials connected with the length of intercalated n-alkylamine, incorporated Si/Ti molar ratios and the solvothermal treatment temperature. The structural evolution of SiO2-TiO2 pillared layered manganese oxide nanohybrid was characterized by XRD, DSC-TGA, SEM. IR, N-2 adsorption-desorption and element analyses. TiO2 particles exhibited a stronger affinity for the negatively charged manganese layers, and the TiO2 particles incorporated were independently intercalated without any distinct chemical bonding with the co-intercalated SiO2 particles. SiO2-TiO2 pillared layered manganese oxide nanohybrid had a BET surface area of 98 m(2)/g with a gallery height of about 1.43 nm between layers. The obtained Sio(2)-TiO2 co-pillared layered manganese oxide nanohybrid is expected as a selective catalyst, or an improved battery material. (c) 2006 Elsevier Inc. All rights reserved.
