Abstract：

The　utilization　of　TiO2-based　photocatalysts　for　an　efficient　removal　of　dye　pollutants　is　limited　due　to　their　low　surface　area,　high　recombination　rate　of　the　photo-generated　electrons　and　holes　and　an　insufficient　absorption　of　sunlight　with　only　3–4%　use　of　solar　energy.　Based　on　this　background,　we　have　successfully　fabricated　a　carbon　nitride　quantum　dots　(CNQDs)-modified　mesoporous　TiO2–SiO2　(Me-TSCN)　via　a　simple　calcination　method　since　the　mesoporous　structure　is　expected　to　induce　a　great　increase　in　the　specific　surface　area　by　carbon　nitride　quantum　dots,　being　favorable　for　the　adsorption　of　the　reactant　molecules　and　the　mass　transfer　of　the　reaction　products.　Furthermore,　such　CNQD　modification　facilitates　the　separation　of　photo-generated　electrons　and　holes.　As　a　result,　the　composite＇s　modification　with　structural　design　could　significantly　improve　the　photocatalytic　activity　of　TiO2-based　catalysts,　achieving　outstanding　photocatalytic　activity　in　the　degradation　of　dye　pollutants　such　as　rhodamine　B.　©　2019,　Springer　Nature　B.V.
