NITROGEN-DOPED TiO2 NANOPARTICLES AND THE USE THEREOF IN PHOTOCATALYSIS

摘要

The invention relates to a photocatalyst that is active under irradiation with UV light, visible light and sunlight, comprising a powder or a ready-to-use nanometric suspension of nitrogen-doped TiO₂, wherein the brookite crystalline phase is also present and whose doping nitrogen content (% by weight) is sufficient to ensure photocatalytic activity in the visible region. The photocatalyst can be easily applied to substrates of varying nature.
