 Recent research has focused on the synthesis, dispersion, and surface modification of three common oxides, titanium dioxide, zinc oxide, and cerium oxide, for use in photocatalysis, UV protection, and sunscreen applications. Gas phase and liquid phase syntheses have been developed, as well as methods for generating weakly aggregated particles with varying compositions, morphologies, and sizes. Deaglomeration techniques have also been explored, along with the challenges associated with stabilizing these particles in aqueous and non-aqueous environments. Measurements of the hammocker constant and isoelectric point have been conducted, along with studies of additives used to create stable dispersions. Transparent photocatalysts, UV protective coatings, and UV blocking sunscreens have all been developed using these oxides.
