Photoprotection of TiO2 Using Propenoic Acid Esters

Titanium dioxide (TiO2) is known to be photocatalytically active. Even with surface modifications, it catalyzes the decomposition of organic materials and promotes the formation of reactive oxygen species. However, a particular propenoic acid ester is shown here to protect TiO2 from inducing such reactions, making it a more effective and safer UV filter.
