Abstract
光觸媒在光源照射下利用特定波長光源的能量來產生電子與電洞，催化周圍之氧氣及水分子激發成極具活性的OH.及O2- 自由基，這些氧化力極強的自由基幾乎可分解所有對人體或環境有害的有機物質及部分無機物質，因此也具有殺菌的作用。
Photocatalysts, once exposed to light source of specific wavelength, can produce electrons and holes, which can react with water and oxygen to generate reactive hydroxyl free radicals and superoxide ions, respectively. Almost all types of organic and inorganic substances can be degraded by using photocatalysis, thus generating bactericidal effect.
