Effect of Photocatalysts Preparation Methods and Light Source on Orange II Photocatalytic Degradation

The objective of the present work was to synthesize 10 wt % metal doped TiO2 (Degussa P-25) photocatalysts using three methods: complex precipitation (CP), depositionprecipitation (DP) and wet impregnation (WI) methods and to evaluate their performance for a model azo dye, Orange II. The raw ph...
