The effect of composite configurations of Fe ionic spins on the dielectric properties in Sm-doped CeFeO3 ceramics

Novel electrode material based on coral-like cerium orthoferrite (CeFeO3) for efficient alkaline water splitting

“…The observed peaks are in accordance with the vibrational structure characteristic of CeFeO 3 , as documented in the literature. 14,15 These findings serve to substantiate the results derived from powder X-ray diffraction, underscoring the phase purity of the synthesized CeFeO 3 specimen.…”

“…Within rare-earth orthoferrites featuring an orthorhombic structure and space group Pbnm, an expectation of 24 Raman-active vibrational modes emerges (7A g + 7B 1g + 5B 2g + 5B 3g ). 14 The obtained Raman spectra revealed distinct peaks at 145.0 cm À1 , 190.7 cm À1 , 426.7 cm À1 , that were attributed to B 1g and B 3g modes, as well as additional peaks at 276.5 cm À1 , 316.9 cm À1 , 442.3 cm À1 , assigned to A g mode. The observed peaks are in accordance with the vibrational structure characteristic of CeFeO 3 , as documented in the literature.…”

Flexible Three-Dimensional Hierarchical Porous Multifunctional Electrodes for Enhanced Performance by Electrodepositing Perovskite CeFeO3 on Carbon Foam

“…These CV and EIS results further confirm that CFO/GF-6m-900 is superior to other samples to exhibit excellent electrochemical performance, agreeing well with the above galvanostatic results, and the optimal synthesis conditions are a calcination temperature of 900 °C and an electrodeposition duration of 6 min. A lower or higher calcining temperature is not good for the electrochemical performance of the as-obtained CFO/GF composite samples, and the possible reasons are as follows: a higher temperature may lead to the collapse of the pore structure of GF (as shown in Figure S3), while a lower temperature is not beneficial for the formation of CeFeO 3 with good crystallinity. ,, On the other hand, due to the poor electrical conductivity of perovskite CeFeO 3 , the electrochemical performance of the composite cathodes is not directly proportional to the added content of CeFeO 3 . Therefore, the CFO/GF-6m-900 sample has the best electrochemical performance and is chosen for further analysis.…”
