Rare　earth　doped　TiO2　catalytic　material　has　promising　applications　in　the　effective　degradation　of　organic　pollutants.　Lanthanum　doped　TiO2　films　were　prepared　by　a　facile　solvothermal　method　using　tetrabutyl　titanate　as　titanium　source.　And　facets　were　controlled　by　preferably　non-metallic　ion　modulating　agent.　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　energy　dispersive　spectroscopy　(EDS)　were　used　to　characterize　the　structures,　morphologies　etc.　of　the　products.　The　photocatalytic　performances　of　the　products　were　measured　by　degradation　of　methylene　blue　as　the　model　organics.　A　series　of　characterizations　illustrate　that　combining　modification　of　doping　can　improve　the　photocatalytic　performance　to　varying　degrees.　Importantly,　the　La　doped　TiO2　films　show　great　potential　in　detoxification　of　harmful　pollutants　in　wastewaters　and　other　catalytic　applications.
