 Abstract
This study was performed to study the photocatalyst for controlling the pollutant such as CO, C2H5OH and H2S by the UV light. This was shown in a catalyst having the same volume and the same surface area, that the structure in which the UV light to reach the interior structure exhibits more excellent activity. However, the activity of this activity of this photocatalyst removal of CO was very low. This problem can be solved by performing a reduction process by the addition of the precious metal series of Pt. Particularly, the amount of chemical species Pt0 incerased in the surface of Pt/TiO2 photocatalyst through the reduction process, which make the reaction activity of photocatalyst excellent to the removal of the CO.
