A combined ToF-SIMS and XPS study for the elucidation of the role of water in the performances of a Post-Plasma Process using LaMnO3+δ as catalyst in the total oxidation of trichloroethylene

- Water promotes the cleaning of the perovskite active sites.
- Water is able to tune the degradation pathway of dichloroacetyl chloride.
- Detection of CH2Cl+ and CHCl2+ by ToF-SIMS on the catalyst in dry air.
