The　TiO2　membranes　were　prepared　on　glass,　ceramic　tile　and　aluminum　pieces　by　Sol-Gel　and　PVD　methods.　A　fast　and　exact　evaluation　on　the　photocatalytic　self-cleaning　performance　of　the　membrane　materials　was　achieved　by　FTIR-ATR　technique　using　oleic　acid　which　was　laid　on　the　surface　of　the　membrane.　The　hydrophilic　property　of　the　samples　was　also　determined　by　the　contact　angle　with　water.　The　results　showed　that　both　the　TiO2　membrane　prepared　on　glass　by　the　Sol-Gel　and　PVD　methods　displayed　good　photo-induced　hydrophilic　property　and　degradation　activity　of　oleic　acid,　and　no　difference　in　hydrophilic　property,　but　the　former　was　a　little　superior　to　the　latter　in　photocatalytic　activity.　The　photocatalytic　conversion　of　oleic　acid　on　the　TiO2/galss,　TiO2/ceramic　tile　and　TiO2　/　aluminum　piece　were　92%,　85%　and　46%,　respectively　after　illumination　3.5　h,　showing　a　distinct　effect　of　support　material　property　on　TiO2　photocatalytic　performance.　The　results　suggested　that　the　photocatalytic　activity　of　TiO2　membrane　coated　on　insulator　support　was　higher　than　that　coated　on　conductor　support.
