The preparation and oxygen sensitivity of strontium ferrite thin films

Investigation of local structure effect and X-ray absorption characteristics (EXAFS) of Fe (Ti) K-edge on photocatalyst properties of SrTi(1−x)FexO(3−δ)

“…Recently, perovskite strontium titanate ferrite, SrTi (1Àx) Fe x O (3Àd) (STF in short), was found to possess redox behavior [18], gas sensing [12,14,20], fuel cell properties [12,20,21], oxygen separation membranes [22] and phase shifters in communication systems [23]. In terms of the bandgap energy of the SrTi (1Àx) Fe x O (3Àd) , with increasing iron concentration of x from 0 to 1, the bandgap moves from 3.17 eV for SrTiO 3 to 1.80 eV for SrFeO 3 [10,16,20,24], which increases the visible light absorption of the STF.…”

Correlation between site preference and magnetic properties of substituted strontium ferrite thin films

“…Hexagonal strontium ferrite (SrFe 12 O 19 , SrM in short) as well as barium ferrite (BaFe 12 O 19 , BaM in short) thin films have fairly large magnetocrystalline anisotropy constant, excellent chemical stability and mechanical strength [1][2][3]. There are several literatures regarding the magnetic and microwave properties of hexagonal ferrite films [4][5][6][7].…”

Multifunctional catalysts toward methanol oxidation in direct methanol fuel cell

“…For example, Mukasyan et al [21] reported that a variety of ABO 3 /Pt compositions with Ru at B-site exhibit comparable performance with Pt-Ru alloy. It is a major constituent of many new materials exhibiting high oxygen-ionic and electronic conductivity [22,23], which have great potential for use in high-temperature oxygen-permeable membranes, electrodes for oxygen sensors, oxygen pumps, fuel cells, solid-electrolyte devices [24], redox behavior [25], and gas-sensing properties [26,27]. The stoichiometrically compositional SrFeO 3 has a simple cubic perovskite structure (a = 3.85 A°) [28,29].…”
