Structural, optical, magnetic and photoelectrochemical properties of (BiFeO3)1−x(Fe3O4)x nanocomposites

Novel photoactive magnetic semiconductor nanocomposites with potential magneto-optical properties

“…Another aspect worthwhile noticing is that, as far as we know, there is no literature available to contrast the obtained results in this study because it is the first time this type of nanocomposites has been synthesized with our methodology. However, the exhibited magnetic and optical properties for such MNPs-BFO nanocomposite, show similar behavior as those reported for similar systems synthesized by other methods (Baqiah et al 2019), and it could be a promising candidate in the development of new devices based on magnetically induced optical properties and magnetically activated photocatalysis (Tong et al 2015).…”

Preparation and photoelectrochemical properties of BiFeO3/BiOI composites

“…[1][2][3] As a typical representative of ferroelectric materials, the internal electric eld induced by self-polarization can facilitate the separation of photogenerated electrons and holes, since the special electric eld modulates the chemical potential and surface band bending, which play a crucial role in improving the photoelectrochemical (PEC) properties. [4][5][6] However, the PEC activities of BFO are still unsatisfactory because of its poor charge transport properties and electronhole recombination. [7][8][9] Based on this situation, many strategies have been proposed to obtain better PEC performances of BFO.…”

“…Wang et al 3 adapted a BFO thin lm with a cobalt-phosphate cocatalyst by a photoassisted electrodeposition method, obtaining a photocurrent density nearly 8 times that of the bare BFO electrode. Baqiah et al 4 introduced Fe 3 O 4 into the BFO matrix to improve the photocurrent performance by narrowing the band gap and reducing the recombination of electron holes. Bera et al 5 decorated BFO nanosheets with Au, and the surfaceplasmon effect (SPR) of Au nanoparticles beneted the generation of photoelectrons and holes.…”

Analysis of the thermal stability and optical properties of KBiFe2O5perovskite obtained by a polymeric precursor method

“…1 KBFO was first studied by Zhang et al 1 to develop a more versatile material than BiFeO 3 (2.6 eV). [6][7][8] In the same study, it was reported that KBFO belongs to the brownmillerite family, which is classified in the group of oxygen-deficient perovskites. Moreover, it has two crystalline structures, one of the orthorhombic type, which is metastable and obtained at temperatures below 575 • C, and above this temperature, it undergoes an irreversible change to monoclinic.…”
