Titanium dioxide is one of the most powerful semiconductor that chemically stable and widely used in the photodegradation of wastewater process. However, titanium dioxide have wide band gap (3.2eV) which only can be activated by using UV light. In order to overcome the weakness of this photocatalyst, the doping technique by using sol-gel method applied to the titanium dioxide. Nitrogen and magnesium were used as dopand.  Thus, in this study, nitrogen and magnesium doped TiO2 will be applied on Reactive Black 5 dye to study the photocatalytic performance and the result will be analysed.
