Abstract Partial oxidation of methane (POM) by chemical looping with CO 2 co-feeding on La 0.8 Sr 0.2 FeO 3 (LSF) perovskite catalyst yielded a highly selective operation and enabled to extend the duration reduction cycle. In this work, conversion syngas was studied Fe (x) Co (1-x) O (x = 0, 0.25, 0.5, 0.75) perovskites in chemical-looping mode, methane. The reaction conducted at 850 °C, 15 min...

We investigate structural and transport properties of highly Ru-deficient SrRu0.7O3 thin films prepared by molecular beam epitaxy on (001) SrTiO3 substrates. To distinguish the influence two types disorders in films, Ru vacancies within lattices near interface, with various thicknesses (t = 1-60 nm) were prepared. It was found that former dominates electrical magnetic when t > 5-10 nm, while la...

This work reports the growth of crystalline SrHfxTi1−xO3 (SHTO) films on Ge (001) substrates by atomic layer deposition. Samples were prepared with different Hf content x to explore if strain, from tensile (x = 0) to compressive (x = 1), affected film crystallization temperature and how composition affected properties. Amorphous films grew at 225 °C and crystallized into epitaxial layers at ann...

The novel polycrystalline Bi0.85Gd0.15CuxFe1-xO3 (x = 0, 0.025, 0.05, 0.075, 0.10) multiferroics are synthesized by the usual solid-state reaction route. synthesis of desired phase has been verified X-ray Diffraction (XRD) patterns. With major structural phases, few traces secondary phases Bi2Fe4O9 and Bi25FeO40 appear for all compositions. A discontinuous series changes with varying compositio...

The performance of LaMnxNi1-xO3±δ perovskite mixed oxides (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1) which were prepared by different methods, the Pechini and sol-gel methods in the oxidation of greenhouse gases, CH4 and CO, has been investigated. All samples were characterized using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electr...
