Mixed oxides of nickel, magnesium and aluminum prepared by precursors hydrotalcite type were substituted by lanthanum or cerium and were characterized by XPS; EDS; BET; XRD; TPR. The catalysts were tested in the POM and the results showed that the catalysts promoted led to a reduction in the velocit...
