Abstract：

Tubular　kaolinite　as　a　support　was　obtained　by　the　exfoliation　and　rolling　of　cetyltrimethylammonium　chloride　replacement　reaction　with　kaolin/methanol　intercalation　compound.　TiO2　doped　tubular　kaolinite　catalysts　were　prepared　by　sol-gel　method　in　aqueous　solution　of　nitric　acid.　The　structural　and　morphological　of　kaolinite　and　its　intercalation　compounds　were　investigated　by　XRD,　FT-IR　and　FE-SEM.　Compared　with　pure　TiO2,　composite　catalyst　has　obvious　enhancement　in　the　utilization　ratio　of　light　absorption,　especially　in　the　visible　range.　The　photocatalyst　efficiency　of　TiO2　doped　tubular　kaolinite　has　increased　by　30%　on　the　degradation　of　methyl　orange　in　aqueous　solution,　after　irradiation　for　30min　under　500W　mercury　lamp.
