Bi OCl photocatalyst was synthesized successfully with bismuth nitrate and potassium chloride as raw materials and glycol as the solvent. Its structure,morphology and optical absorption property were characterized through XRD,SEM and DRS. The results show that the as-prepared Bi OCl was pure phase tetragonal crystal with a globular shape and a band gap of 3. 26 e V. The photocatalytic activity of Bi OCl was evaluated with phenol as the target. After 600 min irradiation with 365 nm monochromatic light,75% of phenol was photo-degraded,but the mineralization rate only attained 14. 8%. This indicated that the disappearance of characteristic diffraction peak strength of phenol did not indicate the fully mineralization of phenol. Further,the photocatalytic degradation mechanism of phenol was investigated by mass spectrometry.
