Mechanochemically assisted synthesis of yttrium ferrite ceramic and its visible light photocatalytic and magnetic properties

Enhanced Multiferroic Properties of YFeO3 by Doping with Bi3+

“…This increment may be explained by the increase in oxygen vacancies propitiated by Bi 3+ cation in the samples. Oxygen vacancies are common as an inherent defect produced by heat treatment or doping in perovskite oxide structures [3,40].…”

Synthesis, characterization and synergistic photocatalytic properties of yeast-assisted composite La0.7Sr0.3MnO3/TiO2

“…It is well known that multifunctional homogeneous photocatalysts with intrinsic magnetic properties can be recycled via a magnetic eld. Therefore a lot of homogeneous catalysts with magnetization and photocatalytic properties have been prepared and the corresponding properties investigated recently, for example, rare-earth mixed chalcogenide Dy 4 S 4 Te 3 , 1 multiporous ZnFe 2 O 4 nanotubes, 2 Ni 2 FeVO 6 nanoparticles, 3 (La 0.5 Bi 0.2 Ba 0.2 Mn 0.1 )FeO (3Àd) , 4 porous tetragonal-CuFe 2 O 4 nanotubes, 5 Ba-doped BiFeO 3 nanoparticles, 6 ferromagnetic ZrO 2 nanostructures, 7 CdS nanostructures, 8 Bi 5 Fe 0.95 Co 0.05 Ti 3 -O 15 via europium doping, 9 yttrium ferrite ceramic 10 etc. Because of the excellent magnetism and photocatalytic activity of perovskite oxides under solar irradiation, it has become the focus of our research group and some perovskite oxides have been investigated and reported, such as LaFe 0.5 Mn 0.5Àx O 3Àd , LaFe 0.9 Mn 0.1Àx O 3Àd , La 0.8 Ba 0.2 Fe 0.9 Mn 0.1 O 3Àd and La 0.8 Sr 0.2 Mn 1Àx -Ti x O 3Àd (x ¼ 0-0.15).…”

Enhanced gas sensing performance of perovskite YFe1−xMnxO3 by doping manganese ions

“…3a, Fe element doped in YFe 0.95 Mn 0.05 O 3 exists in mixed valence state, the Fe 2p 3/2 peaks at 710.5 and 712.5 eV could be assigned to Fe 2+ and Fe 3+ ions, respectively. 18,36 As shown in Fig. 3b, the Mn 2p region consists of a spin-orbit doublet of Mn 2p 3/2 and Mn 2p 1/2 , and the Mn ions doped in YFe 0.95 Mn 0.05 O 3 also exist in mixed valence state.…”

“…14 Among these perovskites, yttrium orthoferrite (YFeO 3 ) has attracted the attention of researchers due to their excellent magnetic, magneto-optical, physical and chemical properties originated by their ionic and electronic defects as well as structure distortions. [15][16][17] To the best of our knowledge, most previous studies on YFeO 3 have been focused on its photoluminescence, catalysts and magnetic properties, [18][19][20][21][22] but few have been reported on gas sensing. In terms of actual sensing requirements, controlling and monitoring the toxic, inammable and explosive gases, such as formaldehyde (CH 2 O), ethanol (C 2 H 6 O) and hydrogen peroxide (H 2 O 2 ), is important for industrial production, indoor life and public safety.…”
