1.UV光催化氧化設備簡介

?TiO2光催化氧化原理：

在光照下，如果光子的能量大于半導體禁帶寬度，其價帶上的電子（e-）就會被激發到導帶上，同時在價帶上產生空穴（h+）。當存在合適的俘獲劑、表面缺陷或者其他因素時，電子和空穴的復合得到抑制，就會在催化劑表面發生氧化還原反應。價帶空穴是良好的氧化劑，導帶電子是良好的還原劑，在半導體光催化反應中，一般與表面吸附的H2O、O2反應生成.OH和超氧離子O2-，能夠把各種有機物直接氧化成CO2和H2O等無機小分子，電子也具有強還原性，可以還原吸附在其表面的物質。激發態的導帶電子和價帶空穴能重新合并，并產生熱能或其他形式散發掉。

光催化的技術特征：

1）低溫深度反應

光催化氧化可以在室溫下將空氣中的有機污染物氧化。

2）綠色能源

光催化可利用太陽光作為能源來活化光催化劑，驅動氧化還原反應，而且光催化劑在反應中并不消耗。從能源角度而言，這一特征使光催化技術更具優勢。

3）氧化性強

大量研究表明，半導體光催化具有氧化性強的特點，對臭氧難以氧化的某些有機物都能有效地加以分解。

4）壽命長

理論上，光催化劑的壽命是無限長的。

5）廣譜性

光催化對從烴到墻酸的眾多種類有機物都有氧化效果，美國環保署公布的九大類114中污染物均被證實可通過光催化氧化法降解。

1. introduction of UV photo catalytic oxidation equipment
The principle of TiO _ 2 photocatalytic oxidation:
Under the light, if the energy of the photon is greater than the width of the semiconductor band gap, the electron ( e - ) of the valence band will be excited to the conduction band, while generating holes ( h + ) in the valence band. When a suitable capture agent, surface defect or other factors exist, the recombination of electrons and holes is suppressed, and oxidation-reduction reactions occur on the surface of the catalyst. Valence band hole is a good oxidant, conduction band electron is a good reducing agent, in the semiconductor photocatalytic reaction, generally with the surface adsorption of H2O, O2 generation reaction generation. oh and O2 - O2 -, can direct oxidation of various organic matter to inorganic small molecules such as CO2 and H2O, electron also has strong reducibility, can restore the adsorption on its surface of the substance.
