TiO2 pillared porous manganese oxide nanocompound with high TiO2 amount was successfully synthesized from birnessite(H)-type manganese oxide (H-BirMO) by intercalation of alkylamine followed by solvothermal treatment in pure titanium isopropoxide (TIIP) liquid. The effects of solvothermal treatment temperatures and chain length of preintercalated alkylamine molecules on the pillared structure were systematically investigated. The amount of intercalated TiO2 depended on the solvothermal treatment temperatures and the water amount in samples, but not depended on the basal spacing of the alkylamine-intercalated intermediate samples. TiO2 pillared porous manganese oxide nanocompound with high TiO2 amount had a BET surface area of 114 m2/g with a galley height of about 1.76 nm between layers. The structural evolution of TiO2 pillared porous manganese oxide nanocompound was characterized by XRD, SEM, N2 adsorption–desorption, IR, TGA–DSC and element analyses.
