Photoprotection of TiO2 Using Propenoic Acid Esters

By: Robert S. Hu, Jean Zhang, Gary A. Neudahl and …

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.
