| Résumé : |
Solar energy is one of the few renewable energy available. Among the solar photoreactions, photo-catalysis is the most widely studied and solar photovoltaic (PV) are the fastest-growing energy technology in the world today, where, an efficient and cost optimizing technologies are required for the removal of air pol lutant and generation of electricity. In th is review paper, we are focusing on abatement of various air pol lutants by photo-catalytic paint technique. We are also discussing an Photovoltaic Paint (N POPV) System for generation of electricity and both this techniques are dependent on natural resource "Sunlight". In addition, the future re-search directions were also presented in this paper. |

- Fig. 1 : Suggested mechanisms for photocatalytic reaction of TiO2 at the valence and conduction band
- Fig. 2: Presents the schematic of photocatalytic oxidation using TiO2 as the photo-catalyst During the photocatalytic oxidation, the most important step of photo-reaction is the formation of hole electron pairs which need energy to overcome the band gap between the valence band (VB) and conduction band (CB). hen the photon energy is equal to or exceeded the band gap energy Eg, the electron-hole pairs are created in the semiconductor, dissociating into free photoelectrons in the conduction band and photo-holes in the valence band respectively
