Structural stability and electrical transport in SrFe1−xMoxO3−δ

Hydrogen production by autothermal reforming of methane: Effect of promoters (Pt, Pd, Re, Mo, Sn) on the performance of Ni/La2O3 catalysts

“…These results are consistent with several other observations[39][40][41][42]. At higher substitution degree x = 0.05 realized for Re, Mo and Sn, formation of perovskite-type oxide ionic radius of a promoter metal.…”

Oxygen non-stoichiometry and defect equlibria in CaMnO3 − δ

“…When the enthalpy ΔH D for reaction 2 is large enough, electrons and holes are strongly localized. Typical oxides with localized electron defects are ferrites La 1−x Sr x FeO 3−δ and their doped derivatives where ΔH D , varies within 1.5-2 eV [5,6,[11][12][13][14]. Manganites La 1−x Sr x MnO 3−δ give another example where the approximation of localized electron defects Mn 0 Mn and Mn Mn results in sufficiently good property description [7].…”

Nano-domain states of strontium ferrites SrFe1−MO2.5+ (M=V, Mo; y≤0.1; x≤0.2)

“…The structure of compounds with the highest oxygen mobility (for example, SrFe 0.95 Mo 0.05 O 2.5 þ x [9]) has very high microstrains relative to other solid solutions. Strained atom bonds should distort the Coulomb fields in the material and change the crystal lattice energy.…”

“…The "order-disorder" phase transitions in case of nanostructured oxides do not lead to destruction of the materials. At the same time, despite the presence of high-charged cations, which are obstacles to the motion of vacancies, doping has a weak inhibitory effect on oxygen diffusion [9][10][11], and in cases of relatively low substitution degree, for example M ¼Mo 6 þ and y¼ 0.05, even improves the diffusion [9].…”
