Preparation of BaSnO₃ and Ba_0.96La_0.04SnO₃ by reactive core–shell precursor: formation process, CO sensitivity, electronic and optical properties analysis

Abstract

A facile method for preparing pure and La doped BaSnO3 by reactive core–shell precursor was proposed and clear evidence of conduction band filling in La doped BaSnO3 was presented.

In situ encapsulation of iron(0) for solar thermochemical syngas production over iron-based perovskite material

“…During the regeneration process, the oxide layer can deliver oxygen to inner Fe 0 coupled with the oxidation of Fe 0 species in oxidizing atmosphere, while the confined Fe species in the core area of particle re-enter the perovskite lattice. Various studies on the kinetics of solid reaction showed that the fabrication of core-shell structure could accelerate the formation of perovskite, since the contact area of the reactants is normally larger while the ion diffusion distance is decreased 47,48 . For LaFeO 3 , La 2 O 3 phase appeared obviously after 20 cycles as shown in Supplementary Fig.…”

Structural and impedance spectroscopy characteristics of BaCO3/BaSnO3/SnO2 nanocomposite: observation of a non-monotonic relaxation behavior

“…The d -spacing's equal to 0.328 nm, 0.172 nm, and 0.281 nm correspond to the (110), (113), and (110) crystal planes of SnO 2 , BaCO 3 , and BaSnO 3 , respectively. 29 …”

“…This is likely to change the electrical performance due to contrasting properties depending upon the type of forming system and the mixed solid solution. 16 It includes phase transition (ferro–paraelectric), dielectric and alternates (increase/decrease) in resistance with temperature and frequency. 17 The obtained modification makes this material suitable and useful for many industrial applications.…”
