DOIAbstract
− A series of manganese base oxides (MnCe, MnZr and MnCeZr) obtained by coprecipitation, were characterized by SBET, XRD, TPR, XPS and studied by FTIR in the oxidation reaction of a typical Cl-VOC such as chloroform, CHCl3. The oxides were compared with a manganese oxide obtained from the recycling of spent batteries (MnOx). In addition, the catalytic combustion of CHCl3 in a fixed-bed reactor was analyzed and the CHCl3 conversion decreased in the order: MnZr > MnOx = MnCeZr >MnCe. In all cases, the conversion is higher than that obtained without a catalyst. The surface Mn4+/Mn3+ ratio would favor the decomposition of Cl-VOC. The study of CHCl3 reaction atmosphere by in situ IR reveals that in the absence of catalysts, CCl4, COCl2, C2Cl4 an...
