The　biggest　challenge　for　the　paint　industry　is　to　clean　the　contaminated　waste　dye　solution　before　it　released　into　the　water　or　to　reuse　it　to　create　new　paint　and　to　protect　the　water　from　environmental　pollution.　Here　in　this　work,　exfoliating　layered　transition　metal　dichalcogenide　materials　prepare　to　the　exfoliated　2D　materials　thin　sheets　in　water　with　the　assistance　of　natural　saponin.　Then,　the　three-dimensional　(3D)　MoS2-aerogel　composite　was　synthesized　by　using　greenway　exfoliated　two-dimensional　(2D)　MoS2　thin　sheets　to　form　MoS2-aerogel　composite.　The　prepared　3D　MoS2-aerogel　composite　demonstrates　excellent　94%　methylene　blue　(MB)　dye　adsorption　ability　over　5　min.　Moreover,　the　adsorbed　MB　of　the　MoS2-aerogel　shows　∼80%　dye　degradation　activity　in　the　presence　of　visible　light.　Therefore,　these　synthesized　3D　MoS2-aerogel　composite　could　be　an　excellent　candidate　for　photocatalytic　applications　in　the　future.　©　2021　Elsevier　Ltd
