Copper and nickel catalysts supported on praseodymium-doped ceria (PDC) for the water-gas shift reaction

The aim of this work is to study the behavior of Cu and Ni catalysts supported on praseodymium-doped ceria (PDC) for the WGS reaction. Samples were prepared by impregnation of several PDC supports (praseodymium content in the range 0–50 wt%) synthesized by the urea thermal decomposition method. Bare...
