| Abstract: Mixtures of H2Ti2.8Mn0.2O7, CH3(CH2)9NH2, and Si(OC2H5)4 at molar ratios of 1∶2∶20 resulted in swollen and viscous gel once at room temperature, allowing the intercalation compound in which CH3(CH2)9NH2 and Si(OC2H5)4 were simultaneously intercalated into interlayers of H2Ti2.8Mn0.2O7. The subsequent hydrolysis of the obtained intercalation compound in pure water solution for 30min at room temperature led to the formation of a new layered H2Ti2.8Mn0.2O7 sample with an interlayer spacing of 3.85nm. Calcination of this sample in air at 500℃ gave rise to a novel mesoporous(d=3.3nm) silica-pillared layered H2Ti2.8Mn0.2O7 with a large BET specific area of 624m2·g-1 and a super-gallery height of 3.24nm. |
