摘　　要：Hierarchically mesoporous titanosilicate Ti-SBA-1 was synthesized with organic mesomorphous complexes of polyelectrolyte（poly（acrylic acid）（PAA）） and cationic surfactant（hexadecyl pyridinium chloride（CPC）） as template, tetraethylsiloxane as silica source and titanium ethoxide as titanium source.By adjusting the amount of titanium ethoxide in the synthesis, a series of Ti-SBA-1 particles with different Si/Ti ratio（79–180） were prepared. After incorporation of Ti into the silica framework the wellordered cubic Pm3n mesostructure remained, as well as the morphology, particle size. UV–vis DR spectra of the Ti-SBA-1 materials indicated that incorporated titanium species existed in a highly dispersed state and exhibited tetrahedral and octahedral coordination in the silica framework.Hierarchically mesoporous titanosilicate Ti-SBA-1 was synthesized with organic mesomorphous complexes of polyelectrolyte（poly（acrylic acid）（PAA）） and cationic surfactant（hexadecyl pyridinium chloride（CPC）） as template, tetraethylsiloxane as silica source and titanium ethoxide as titanium source.By adjusting the amount of titanium ethoxide in the synthesis, a series of Ti-SBA-1 particles with different Si/Ti ratio（79–180） were prepared.
