제목 | Tailored synthesis of graphene supports for high performance low temperature SCR catalysts |
초록 | Selective Catalytic Reduction technology is a typical technique used to remove Nitrogen oxides (NOx), which is a major source of industrial particulate matter (PM). Recently, as the application of SCR catalysts are expanded, the needs for the low temperature SCR catalyst which have high NOx removal efficiency at low temperature region ( 250 oC) increased. In this study, various types of graphene supports were applied to improve the dispersion properties of active materials in order to synthesize SCR catalysts with high NOx removal characteristics. Since the catalytic reaction is surface reaction, graphene supports having higher dispersion characteristics are applied such as rGO, GO, porous graphene and surface treated graphene with N containing functional groups to enhance the catalytic acidity. As results, N-doped graphene added catalysts have high NOx removal characteristic of 90% at 200 oC based on its high thermal stability, dispersion characteristics and surface area properties. |
