제목 | Highly dispersed nanocatalyst using modified support for NH3-SCR reaction |
초록 | These days, there are several issues such as expanding the operating temperature range and demanding higher NOx removal efficiency for SCR catalysts. In order to increase the NOx removal efficiency, it is most important to increase the catalytic reaction site through improvement of specific surface area and to disperse the catalytically active particles on the overall catalyst. When the active materials have low dispersibility, there is a problem that the activity is lowered through catalyst aggregation and crystallization as the content of catalytic materials increases. Here, we conducted a study of nano-dispersing active particles through using the modified graphene support or surface treated TiO2. By adding these support, active materials could be evenly dispersed on the catalyst surface which has abundant anchoring sites with improved specific surface area. And as results, these developed catalyst exhibit high catalytic activity in the wide temperature window. |
