TiO2/RGO　composite　aerogels　with　TiO2　nanostructures　grown　on　interconnected　three-dimensional　RGO　porous　networks　were　fabricated　via　a　facile　one-pot　hydrothermal　method.　The　as-obtained　composite　aerogels　show　controllable　and　continuously　tunable　surface　wettability　from　super-hydrophobic　to　super-hydrophilic　depending　on　the　amount　of　incorporated　TiO2.　The　TiO2/RGO　composite　aerogels　with　varied　surface　wettability　can　selectively　degrade　different　pollutants　in　aqueous　systems.　The　capability　of　forming　the　TiO2/RGO　aerogels　with　tunable　surface　wettability　for　selective　photocatalysis　is　important　since　such　materials　are　especially　useful　in　some　systems　which　contain　extremely　poisonous　contaminants　in　low　concentration　together　with　large　quantity　of　un-poisonous　chemicals.　(C)　2015　Elsevier　ay.　All　rights　reserved.
