| Abstract: | WT5BZ]Titanium dioxide nanoparticles were prepared from cheap inorganic salts by sol-gel and supercritical fluid drying method(SCFD).The photocatalytic degradation of phenol in titanium dioxide suspensoid was investigated. Experiment results showed amount of photocatalyst,TiO 2 crystalline pattern,wave length of ultraviolet light and pH of solution considerably affected the process of degradation.Catalytic activity of different photocatalysts was evalu |
