“…It must be noted that there have been only a few studies regarding LaFeO 3 , while many doped derivatives have been widely studied. Figure shows cations that have been successfully added to LaFeO 3 and which sites (La or Fe) they were determined to occupy. ,− To our best of knowledge, the local structure of undoped LaFeO 3 has not yet been investigated, most likely due to the complexity of magnetic neutron total scattering.…”

Mixed ionic and electronic conductors (MIECs) are being studied extensively as a potential replacement for cermet catalysts in solid oxide cells (SOCs)collectively named for solid oxide fuel cells and solid oxide electrolysis cellsdue to their high activity, great stability, and low cost. Perovskite-type LaFeO3-based catalysts are one of the most promising electrodes for SOCs. This review paper provides an update on the chemical composition–crystal structure–physical property relationships and an understanding of the electrochemical reaction mechanisms in the perovskite-type structure LaFeO3 electrodes. Mechanisms for electrochemical CO2 reduction on the perovskite structure surface and oxygen diffusion are discussed. Furthermore, the electrochemical performance enhancement strategies such as composite electrodes and nanoparticles ex-solution are briefly presented together with industrialization issues, e.g., gas impurities and stability of the interconnecting materials.

In this work, it was highlighted synthesis strategy and fundamental characterization of the pure and Ce doped Ba2TiMoO6 with different Ce concentrations were presented. It was investigated its thermal stability by using the Thermal Gravimetric Analysis and Differential Thermal Analysis. The crystal structures and the purity of the compounds were analyzed by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The Surface morphology was examined by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and surface area analysis. The optical properties were examined by using the UV-Vis diffuse reflectance and photoluminescence (PL) spectroscopies. The prepared Ba2TiMoO6 nanopowders are characterized by band gap of 3.41~3.6 eV and violet emission of 426.67 nm wavelength. The degradation efficiency was found approximately 16% of Methyl Blue (MO) after 120 min duration. Our results will predicate new Perovskites materials, which can be used for future environmental applications.
