First principles study of structural, elastic, electronic, and optical properties of the cubic perovskites AVO3 (A = Ca and La)

Individual and Simultaneous Electrochemical Detection of Allura Red and Acid Blue 9 in Food Samples Using a Novel La2YCrO6 Double Perovskite Decorated on HLNTs as an Electrocatalyst

“…The A site of the perovskite structure can accommodate either a rare-earth or an alkaline earth element, while the B site allows for the presence of two distinct transition metal (TM) elements. This unique arrangement provides a remarkable level of flexibility and freedom, surpassing that of a simple ABO 3 perovskite structure. − The electrical behavior of oxides that contain transition metals is predominantly determined by the interplay between the cations of the transition metals and the anions of oxygen . Layered double perovskites, namely, ReCuM 2 O 5+δ (Re = La, Pr, Sm, Nd, Gd, Y; M = Zr), have garnered significant scientific interest in recent times due to their efficient oxygen-ion transport and surface exchange capabilities. − Rare-earth-based double perovskites have garnered significant attention across various domains, including spintronics, catalysis, magnetic materials, photodetectors, supercapacitors, and electrode materials. − Sr 2 NiMoO 6 double perovskites were synthesized by Liu et al through the sol–gel method and subsequently employed as gas sensors .…”
