New catalytic systems, synthesised by a variant of the citrate route, are proposed for the partial oxidation of methane. They consist of solid solutions – barium, zirconium, rhodium and oxygen – with a perovskite structure of formula BaZr (1−x) Rh x O 3 . Detailed analysis of the XRD diffractograms and the TGA cycles show that Rh is randomly distributed as Rh IV among...
Ni, Rh and Rh/Ni containing catalysts obtained from hydrotalcite type precursors have been studied in the partial oxidation of methane. The catalysts have been characterised by HRTEM to evaluate the effectiveness of the preparation method in the dispersion of the metal. The tests carried out in the partial oxidation of methane at a residence time of 12ms did not allow to enlighten significant differences...
