- Abstract
Photocatalysis has been considered as an advanced oxidation process capable of transforming a large variety of toxic organic pollutants into harmless substances at ambient conditions. However, the use of titanium dioxide as anatase in ceramic products is limited due to transformation to rutile at temperatures higher than 400 °C. The studies show promising ways for inhibiting the formation of rutile through the introduction of dopants in the semiconductor structure. This work is a review of the main aspects found in specialized literature with photocatalytic titanium dioxide, particularly the relationship between chemical structure and photocatalytic activity.
