Effect of calcination temperature on structural properties and catalytic activity in oxidation reactions of LaNiO3 perovskite prepared by Pechini method
K Rida, MA Peña, E Sastre, A Martinez-Arias - Journal of Rare Earths, 2012 - Elsevier
The study presented the preparation of the perovskite oxide LaNiO3 by the complex citrate
method, paying particular attention to evolution of its formation from the amorphous
precursor with varied calcination temperatures. The products obtained after heat treatment
under air between 200 and 800° C were characterized by X-ray diffraction (XRD),
thermogravimetric and differential thermal analysis (TG-DTA), Fourier transform infrared
spectroscopy (FTIR), SBET measurements and X-ray photoelectron spectroscopy (XPS) …
