Graphene　oxide-particle　composite　films　with　filtration　function　have　been　successfully　synthesized　by　a　two-step　method.　First,　graphene　oxide-TiO2　composite　sheets　are　prepared,　which　can　form　stable　dispersion　in　water.　Then,　by　assembling　these　composite　sheets,　graphene　oxide-TiO2　films　are　obtained.　In　these　as-prepared　films,　dilated　space　and　channels　are　desirably　formed　by　introducing　nanoparticles　between　these　carbon　sheets,　making　them　promising　separation　membranes.　We　used　these　films　as　filtration　membranes　to　remove　dye　molecules　(methyl　orange　and　rhodamine　B)　from　water.　The　results　show　that　apart　from　the　adsorption　capacities　of　these　dyes,　these　graphene　oxide-TiO2　films　can　also　capture　additional　amount　of　dye　molecules,　indicating　their　potential　applications　in　water　purification　areas.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
