Abstract	The role of oxygen and the generation of active radicals in the photocatalitic degradation of phenol were investigated using the eosin sensitized TiO$_{2}$ as photocatalyst under visible light irradiation. Diffuse reflectance spectra show that the absorbancy range of eosin/TiO$_{2}$ is expanded from 378 nm (TiO$_{2}$) to about 600 nm. The photocatalitic degradation of phenol is almost stopped when the eosin/TiO$_{2}$ system is saturated with N$_{2}$, which indicates the significance of O$_{2}$. The addition of NaN$_{3}$ (a quencher of single oxygen) causes about a 62% decrease in the phenol degradation. The phenol degradation ratio is dropped from 92% to 75% when the isopropanol (a quencher of hydroxyl radical) is present in the system. The experimental results show that there are singlet oxygen and hydroxyl radical generated in the eosin/TiO$_{2}$ system under visible light irradiation. The changes of absorbancy indicate that the hydrogen peroxide might be produced. Through the analysis and comparison, it is found that the singlet oxygen is the predominant active radical for the degradation of phenol.
