Using　P123　as　a　template　and　TEOS　as　a　silica　resource,　Ce-silica　mesoporous　SBA-15-type　material　was　synthesized　rapidly　via　microwave　technique　and　characterized　by　XRD,　FT-IR,　low　temperature　N2　adsorption-desorption　and　DRS　measurements.　The　results　showed　that　there　exist　two　coordination　states　of　cerium　in　Ce-SBA-15　which　synthesized　when　the　pH　value　of　gel　system　ranged　from　2　to　7.　The　obtained　Ce-SBA-15　possess　the　highest　surface　area　when　the　acidity　condition　was　adjusted　at　pH=2.
