A novel pillaring procedure without alkylamine or tetraalkylammonium pretreatment has been developed to prepare SiO2/TiO2 pillared layered manganese oxide with large surface area. SiO2/TiO2 pillared layered manganese oxide is prepared by solvothermal treating H-type layered manganese oxide at 220 degrees C for 12h in a mixed solution of absolute ethanol, tetraethylorthosilicate, and titanium isopropoxide. The obtained SiO2/TiO2 pillared layered manganese oxide is expected to be a selective catalyst or an improved battery material.
