Low-temperature NO decomposition in humidified condition using plasma-catalyst system

- Plasma-catalyst system provides effective NO conversion under a humidified condition.
- Optimization of the supported metals, oxides, electric factors was conducted.
- Pt is the most active metal and promotes formation of N2 and N2O from NO.
- Both the energy input and metallic surface area of Pt plays important roles.
- The maximum peak current in plasma is extremely important.
