3 steps for the photocatalysic<br />
degradation reaction ot the surface<br />
active agent on the surface of TiO2:<br />
1) Absorption of surface active agent on the<br />
surface of TiO 2 ;<br />
2) Absorption of UV by TiO 2 and the formation of<br />
electron/hole pair ( 电 子 / 空 穴 对 ) (e - /h + ), and the<br />
further reaction between this pair and the<br />
aromatic ring (Ar) of the surface active agent<br />
and the production of aromatic cations (Ar + );<br />
3) The ring-opening process of Ar + , and successive<br />
oxidation to the fnial production of CO 2.
