Novel magnetic Ni-Al hydrotalcite with Ni/Al molar ratio of 3 was synthesized by the hydrothermal method and co-precipitation. The obtained material was characterized in detail by thermogravimetric analysis – differential scanning calorimetry, X-ray diffraction (XRD), transmission electron microscopy (TEM), and vibrating sample magnetometry (VSM). XRD analysis indicated that a more well-crystallized hydrotalcite-like phase and higher thermal stability were present in the hydrothermally treated product than in that obtained by the conventional co-precipitation method. Well-defined flat particles were observed by TEM, and the (200) lattice plane (d = 0.21 nm) could be clearly seen in the HRTEM image. Furthermore, VSM results showed that the obtained material exhibited paramagnetism.
