Abstract
A photochemical reactor element containing microcapsulated TiO,photocatalyst particles dispersed in a polysiloxane matrix is disclosed. The polysiloxane matrix has an oxygen gas permeability not less than 1×10,mol·m·m,·s,·Pa,. The photochemical reactor element is produced by dispersing the microcapsulated or naked TiO,photocatalyst particles in a hydrolyzate-polycondensate sol of a trialkoxysilane or a mixture thereof with a tetra- and/or dialkoxysilane and then shaping the dispersion into the element. The naked TiO,photocatalyst particles in the element are microcapsulated within a porous silica shell layer in situ by irradiating the element with UV radiation.
