Titanium dioxide,isolated titanium ions have been incorporated into microporous and mesoporous silica materials via direct synthesis and post-synthesis. Mesoporous silica SBA-15 has been synthesized and incorporated with titanium via incipient-wetness impregnation with titanate coupling agent KR 44 in ethanol followed by calcination. The results of characterization by TEM, BJH, and FTIR indicate that the incorporated titanate is confined in the channel of silica. Titanate coupling agents are effective in the inclusion of inorganic nanomaterials into mesoporous materials. |
