Resum

La desactivació del TiO2 s'estudia durant l'oxidació fotocatalítica en fase gasosa d'orgànics que contenen tres heteroàtoms diferents: Si, N i S. L'espectroscòpia electrònica Auger s'utilitza per a caracteritzar les espècies de verí dels catalitzadors. Es presenta una equació cinètica que explica l'activitat observada contra dades temporals. Finalment es fa una estimació del nombre equivalent de capes d'un reactiu convertides abans de la desaparició total de l'activitat.
