摘要
The present invention refers to a photocatalytic method for disinfection of interior surfaces and composition of washable biocide paint with photocatalytic properties. The composition is based on acrylic- styrene resins in which was dispersed as photosensitive biocide agent, particles of photosensitized metal oxide semiconductor of type anatase Ti02 or ZnO, oxides that are doped with transition metals like Ag, Au, Cu, Ni, Fe, Cr, Co or Mn, and the biocide properties are activated through a photocatalytic activation Method by irradiating the composition with photons in the visible light spectrum, with wavelengths between 450 nm and 500 nm, which are characteristic for the activation of the dopant from the photosensitized semiconductor of type anatase Ti02 or ZnO, determining the apparition of reactive oxygen singlet species ROS (type 02 I Ag or 02 Eg ), species which have biocide and disinfecting action.
