Photocatalysis step：Exhaust gas after washing enters photocatalysis apparatus 3, the Strong oxdiative generated in photocatalysis apparatus 3
Ion cluster is restored by organic exhaust gas oxygenolysis；Photochemical catalyst TiO2Its electronic structure feature is a full valence band and a sky
Conduction band, under the illumination condition more than its band-gap energy (Eg=3.2ev), electronics can form freedom from valence to conduction band
Electronics, and a positively charged hole is formed in valence band, form electron hole pair；
TiO2+hυ→(TiO2)h++(TiO2)e-
Valence band hole is good oxidant, and conduction band electron is good reducing agent.Hole generally with the H of adsorption2O
Or OH-Ionic reaction forms the activity hydroxy (OH) with strong oxidizing property
h++H2O→·OH+H+
h++OH-→·OH
Electronics then with the oxygen molecule (O of adsorption2) reaction, generate superoxide ion (O2 -).Superoxide ion can with water into
Single step reaction generates perhydroxyl radical (OOH) and hydrogen peroxide (H2O2)
e-+O2→·O2 -
·O2 -+H2O→·OOH+OH-
2·OOH→H2O2+O2
·OOH+H2O+e-→H2O2+OH-
H2O2+e-→·OH+OH-
TiO2Photochemical catalytic oxidation is activity hydroxy (OH) and other active oxidation substances (O2-, OOH, H2O2) altogether
The result of same-action；In TiO2The OH group reactivities of Surface Creation are very high, have higher than all kinds of chemical bonds in organic matter
The reaction energy of energy, in addition O2 -, OOH, H2O2The synergistic effect of active oxidation substance can be decomposed quickly and effectively organic
