Low-temperature synthesis of single-phase crystalline LaNiO3 perovskite via Pechini method

Preparation, surface state and band structure studies of SrTi(1−x)Fe(x)O(3−δ) (x=0–1) perovskite-type nano structure by X-ray and ultraviolet photoelectron spectroscopy

“…E. Bocquet et al [39] used a p-d charge-transfer cluster-model calculation to interpret the Fe 2p core levels. They defined the charge transfer energy Δ eff with respect to the lowest multiplet levels of the d 4 and d…”

“…Perovskite structure material are used in a wide range of applications such as catalysis [1,4], photocatalysis [5,6], fuel cells [7], magnetooptics [8,9], and in spin valves [10]. The stability of perovskite materials at high temperatures and in chemically aggressive atmospheres has made these materials such as SrTiO 3 and BrTiO 3 suitable as gassensor materials [11,12].…”

“…For the Fe 2p core-levels XPS spectra, strong satellite features were observed for the d 5 compounds with an apparently weaker satellite present for SrFeO 3 . Similarly, the spectrum for SrFeO 3 was primarily composed of main peaks due to the screened cd 5 L states and satellite structure from mixed cd 4 and cd 6 L 2 states [59].…”

Structural and electrical properties of Gd(Ni1/2Zr1/2)O3

“…The energy band found in between 600 cm −1 and 664 cm −1 is due to the asymmetric BO 6 stretching vibration arising from the higher charge of the cation. The large width of the band at 600 cm −1 may be due to the overlapping of the ZrO 6 and NiO 6 vibrational modes [18][19][20][21].…”

Synthesis of single phase rhombohedral LaNiO3 at low temperature and its characterization

“…der synthesis routes. Single phase LaNiO 3 was synthesized using a number of methods including conventional ceramic powder technology, nitrate decomposition, pechini method, hydrothermal flow coprecipitation, coprecipitation, to name a few [9][10][11][12][13][14]. Those techniques generally require high temperatures (in excess of 750 • C), flowing oxygen and long calcination periods (usually in excess of 2 h) in order to obtain single phase LaNiO 3 .…”
