Molybdenum　disulfide-based　membranes　have　received　wide　attention　for　their　excellent　performance　in　chemical　separation　field.　Yet,　manipulating　the　structure　of　MoS2　membranes　still　remains　an　unprecedented　challenge.　In　this　work,　the　tubular　MoS2　ceramic　membranes　were　prepared　by　in-situ　hydrothermal　method　using　aqueous　solution　of　thiourea　and　ammonium　molybdate　as　precursor　solution.　The　structure　and　morphology　of　the　membranes　were　manipulated　by　introducing　different　alcohols　into　the　precursor　solution.　The　results　indicated　that　the　presence　of　alcohols　drove　the　transformation　of　MoS2　morphology　from　nano　sheets　to　spherical　aggregates.　As　the　molecular　weight　of　the　alcohols　decreased,　more　small-sized　molybdenum　disulfide　spheres　were　formed　on　the　tubular　ceramic　substrate,　which　resulted　in　the　formation　of　a　great　number　of　large　transportation　channels　and　promotion　of　surface　area,　and　thereby　improved　the　permeability　of　the　membrane.　Moreover,　the　addition　of　different　alcohols　enhanced　the　negative　charge　of　the　membrane　surface,　which　ensured　an　effective　rejection　while　enhancing　the　membrane　permeability.　The　results　demonstrate　that　the　membranes　prepared　in　a　water-ethanol　mixed　solvent　possess　an　excellent　permeability　for　water　(33.2　L/(m(2)　h　bar))　and　methanol　(52.2　L/(m(2)　h　bar)),　with　a　rejection　of　more　than　97%　for　Eriochrome　black　T,　and　an　excellent　pressure　resistance　as　well　as　long-term　running　stability　under　cross-flow　filtration.　In　addition,　such　membrane　exhibited　a　below　30%　rejection　for　salts,　which　can　be　utilized　for　dye　desalination.
