), Chengalpattu district, Kelambakkam, Tamil Nadu, 603103, India 10.3762/bjnano.13.79 Abstract LaFexNi1−xO3 perovskiteoxides were prepared by the sol–gel method under various conditions, including different pH values (pH 0 and pH 7) and different calcination temperatures (500–800 °C) as well as different Fe/Ni
ratios (1/9, 3/7, 5/5, 7/3, 9/1). The samples were examined by XRD, DRS, BET, and SEM to reveal their crystallinity, light-absorption ability, specific surface area, and surface features, respectively. The photocatalytic Fenton reaction was conducted using various LaFexNi1−xO3 perovskiteoxides to
decompose the methylene blue molecules. Accordingly, the synthesis condition of pH 0, calcination temperature at 700 °C, and Fe/Ni ratio = 7/3 could form LaFe0.7Ni0.3O3 perovskiteoxides as highly efficient photocatalysts. Moreover, various conditions during the photocatalytic degradation were verified

semiconductors such as conjugated polymers [8] as well as some perovskiteoxides [9][10][11]. Perovskites have the general formula ABX3, where the A cation in a cuboctahedral site coordinates with 12 anions, and the B cation in an octahedral site coordinates with 6 anions. New perovskite materials under
hand, the manganite oxide perovskites are strongly correlated electron systems that exhibit a strong electron–phonon interaction. This leads to the formation of small polarons [21]. The polaron-like character of the quasi-particles in perovskiteoxides provides at least two exciting issues related to
bending, this leads to sharp discontinuities of the band structure at the interface and is modelled in the framework of a sharp junction [30].
In many perovskiteoxides, the band structure is determined to a large degree by the correlation interactions [31]. Since these correlations strongly depend on the
