Selective Catalytic Reduction (SCR) of Lean NOx using Hydrocarbon by Plasma Enhanced Catalysis over Nano-Size Gold Catalyst Supported on Alumina |
| 초록 |
Nano-sized gold catalysts supported on alumina were prepared and applied to the lean DeNOx reaction by plasma-enhanced catalysis. The average size of metallic gold particles estimated by dark field TEM analysis was 4.5 nm. The plasma-Au/Al2O3 system showed an improved DeNOx activity at low temperatures below 250℃. In case of plasma-2.0wt%Au/Al2O3, NOx conversion was about 40% and N2 yield was 10~30% at 100~250℃. The NOx reduction activity to N2 using hydrocarbon reductant at this temperature range has not been reported yet. This low-temperature DeNOx activity seems to be caused by the increase of Au - alumina interface due to the formation of nano-sized Au particles, which facilitated plasma-activated NO2 and hydrocarbon being adsorbed on the metallic Au and alumina, respectively, migrated and then reacted with each other. |
