Abstract：

La-Ce-silica　mesoporous　SBA-15-type　material　has　been　rapidly　synthesized　using　microwave　technique　and　characterized　by　XRD,　FT-IR,　DRS,　and　low　temperature　N2　adsorption-desorption　measurement.　The　results　show　the　La　and　Ce　were　successfully　incorporated　into　the　framework　of　SBA-15　molecular　sieve　and　the　synthesized　material　not　only　retains　the　hexagonal　order　and　physical　properties　of　purely　siliceous　SBA-15　but　also　possesses　high　surface　area　and　narrow　pore-size　distribution.　Further,　the　obtained　material　La-Ce-SBA-15　was　used　as　catalyst　support　to　load　active　metal　Pt　for　CO　oxidation　reaction.　The　results　of　experiment　indicate　that　the　catalytic　activity　of　Pt/La-Ce-SBA-15　is　higher　than　that　of　the　Pt/SBA-15　and　Pt/La/Ce/SBA-15.　©　Springer　Science+Business　Media,　LLC　2008.
