Removal of dilute VOCs in air by post-plasma catalysis over Ag-based composite oxide catalysts

- The post-plasma catalysis hybrid process reduces efficiently by-product emissions.
- The ozone produced is efficiently decomposed on Ag-based catalysts at room temperature.
- The energy wasted in production of oxygen atoms that recombine to form O3 is recovered.
- Long-term stability of the post-plasma catalytic process is also very satisfied.
