Lanthanum-doped　anatase　TiO2　nanosheet　films　with　exposed　high-reactivity　{001}　facets　were　synthesized　directly　on　transparent　conductive　fluorine-doped　tin　dioxide　(FTO)　substrates　by　a　facile　one-pot　solvothermal　method.　The　surface　morphological　structure　and　crystal　facets　of　the　TiO2　nanosheets　could　be　facilely　controlled　under　appropriate　conditions.　The　photocatalytic　activities　of　the　La-doped　TiO2　nanosheet　films　were　evaluated　for　the　degradation　of　methyl　orange　(MO)　and　methylene　blue　(MB).　The　results　demonstrated　that　the　photocatalytic　activities　of　the　La-doped　TiO2　nanosheet　films　are　higher　than　those　of　the　pure　TiO2　film;　this　is　ascribed　mainly　to　the　synergistic　effect　of　the　La　doping　and　the　high　percentage　of　exposed　{001}　facets.　A　possible　mechanism　for　the　photocatalytic　degradation　of　MO　and　MB　has　also　been　proposed.
