Abstract: Nickel–aluminum–cerium layered double hydroxide (LDH) in carbonate form was successfully synthesized by co-precipitation followed by hydrothermal treatment. The predetermined molar percentage was the following: Ni2+/(Al3+ + Ce3+) = 3 and Ce3+/(Al3+ + Ce3+) = 0.05. The XRD data indicated that the cerium-containing single-phase product with a hydrotalcite structure could be obtained by hydrothermal treatment for 48 h at 120 °C. The transmission electron microscopy analysis showed that the synthesized material consisted of plate-like particles typical for hydrotalcite-like compounds. The average particle size was about 65 nm. The X-ray absorption spectroscopy revealed cerium to be incorporated into the structure of LDH in two different forms, namely 69% of Ce3+ and 31% of Ce4+ co-existed in the structure.
