Description
| - The Ni-Al layered double hydroxides (LDHs) with Ni/Al molar ratio of 2, 3, and 4 were prepared by coprecipitation and treated under hydrothermal conditions at 180 °C. Hydrothermal treatment increased significantly the crystallite size of coprecipitated samples. Gradual crystallization of NiO-like mixed oxide was observed at higher temperatures. Hydrothermal treatment improved thermal stability of the Ni2Al and Ni3Al LDHs but only a slight effect of hydrothermal treatment was observed with the Ni4Al sample. Hydrothermal aging of the LDHs resulted in decreasing content of the amorphous component and enhanced substitution of Al cations into NiO-like structure. The hydrothermally treated samples also exhibited a worse reducibility of Ni2+ components and an increase in pore size with increasing time of hydrothermal aging. The hydrothermal treatment of LDH precursor significantly improved the catalytic activity of Ni2Al mixed oxides in N2O decomposition.
