Catalytic performance of plasma catalysis system with nickel oxide catalysts on different supports for toluene removal: Effect of water vapor

- Complete conversion of toluene was achieved in dry air by the CPC system.
- The presence of water vapor has negative influence on the activity of catalysts.
- Order of durability of catalysts was NiO/TiO2 > NiO/SBA-15 > NiO/γ-Al2O3.
- Catalyst with lower H2O desorption activation energy had better susceptibility.
