PHOTOCATALYTIC ACTIVITY OF TITANIUM DIOXIDE FILMS UNDER VISIBLE LIGHT EVALUATED BY ESI(-)-MS

摘要

Some metal oxides, such as titanium dioxide (TiO2), can be employed as photocatalysts because of their ability to promote oxidation of organic molecules when activated by UV-light [1] due to its wide band gap. In this work, we showed via ESI(-)-MS that thin mesoporous films of TiO2 nanoparticles can degrade hazardous environmental pollutants, as 2-naphtol [2], under visible light incidence.
