Surface application of photocatalyst in cement-based materials could endow it with photocatalytic properties, however, vegas golden knights background the weak adhesion between photocatalyst coatings and the substrates may result in poor durability in outdoor environments.In this study, TiO2@SiO2 core-shell nanocomposites with different coating thicknesses were synthesized by varying the experiment parameters.The results indicate that SiO2 coatings accelerated the rhodamine B removal to a certain extent, owing to its high surface area; however, more SiO2 coatings decreased its photocatalytic efficiencies.The cement matrix treated with TiO2@SiO2 core-shell usc trojans snapback hat nanocomposites showed good photocatalytic efficiency and durability after harsh weathering processing.

A reaction mechanism was revealed by the reaction of TiO2@SiO2 nanocomposites with Ca(OH)2.
