Abstract
In photocatalytic reaction, the doping of metal matter can alter the titania surface properties. As such the metal matter can increase the rate of the reaction. The influence of metal doping and calcination condition of $TiO_2$ photocatalyst was investigated at the batch-type photoreactor. Several metal matters were doped to the $TiO_2$ catalyst to improve photodegradation efficiency. During the experiments, water content was 3wt%, and reactor temperature was $40^{\circ}C$. Palladium-doped $TiO_2$ was found to be the best, where as platinum or tungsten-added also showed good results. Additional doping of platinum or tungsten on Pd/$TiO_2$ had no increase on the removal efficiency. To obtain proper calcination condition, various experiments about calcination temperature and time were carried out. As a result, the optimum calcination condition was temperature of $400^{\circ}C$, time of 1 hour.
