Lire la suite >Fe-doped manganese oxide octahedral molecular sieves (referred as OMS-2) of cryptomelane type structure were synthesized by co-precipitation and impregnation by refluxing at ambient pressure. The influence of Fe in the MnO2 structure was assessed by several characterization techniques such as ICP-OES (inductively coupled plasma-optic emission spectroscopy), X-ray diffraction, Raman spectroscopy, N2 adsorption analysis, H2-TPR (hydrogen temperature programmed reduction), and TGA/DTA (Thermogravimetric analysis/Differential thermal analysis). The co-precipitated sample (Fe-K-OMS-2) shows better performances for TCE removal in moist air when used downstream from a NTP (non thermal plasma) generated in a DC multi-pin-to-plate corona/glow discharge in comparison to the iron free manganese oxide octahedral sieve (K-OMS-2). The enhanced performances towards TCE removal using Fe-K-OMS-2 downstream from the NTP are attributed to high surface oxygen mobility and to an increase of structural defects resulting from improved textural properties. These characteristics allow promoting O3 decomposition and TCE catalytic total oxidation (CTO) efficiencies.Lire moins >
