Photocatalysis Mechanism
Nano-TiO2 photocatalytic degradation mechanism finishes the photocatalytic process
in seven steps:
1. TiO2 + hva eE + h+
2. h+ + H2Oa a cOH + H+
3. eE + O2a a cOOE
4. a cOOE +H+ a a cOOH
5. 2a cOOH a O2 + H2O2
6. a cOOE + eE + 2H+ a H2O2
7. H2O2 + eE a a cOH + OHE
8. h+ + OHE a a cOH
When a photon with energy hv or with energy greater than the semiconductor energy gap Eg is emitted into the semiconductor, an electron is excited from the valence band (VB) to the conduction band (CB), yielding an highly active electron (eE ) in the CB and a hole (h+) in the VB, and forming a redox system. The interactions between dissolved oxygen and water and between electrons and holes result in highly-active a cOHE , a cO2E and a cOOHE . The highly-oxidizing free radicals can decompose most of the organic pollutants on the TiO2 surface into CO2 and H2O, and to oxidize or reduce inorganic contaminants to harmless substances
Application Area
Nano-TiO2 is a good photocatalyst widely used in the fields of air purification, wastewater treatment, paint, cosmetics, plastics, textiles, ceramics, glass.
