In this work, structural and magnetic properties of the LaMnO3+δ compound prepared by citrate precursor method and annealed in the presence of oxygen are investigated.

Layered oxides are promising cathode materials for sodium-ion batteries because of their high theoretical capacities. However, many of these layered materials experience severe capacity decay...

Apr 5, 2013 · X-ray diffraction (XRD) was carried out using a Philips x-ray diffractometer for the bulk powder samples and Panalytical X'Pert Pro diffractometer with Cu Kα radiation for the thin films. Raman spectroscopy (Horiba Jobin Yvon Labram HR 800) was performed at room temperature on these samples.

LaMnO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. La3+ is bonded to twelve equivalent O2- atoms to form LaO12 cuboctahedra that share corners with twelve equivalent LaO12 cuboctahedra, faces with six equivalent LaO12 cuboctahedra, and faces with eight equivalent MnO6 ...

Jan 15, 2023 · XRD pattern of the LMO film heated at 750 °C (Fig. 5) contains two intensive peaks at 23.0° and 46.9°, corresponding to reflections from (001) and (002) planes, respectively.

LaMnO3 perovskite has been regarded as a promising catalyst for the selective catalytic reduction of NOx with CO.

Apr 27, 2014 · Series of characterization techniques including XRD, N 2 sorption, H 2-TPR and O 2-TPD were performed to investigate the correlation between the physicochemical properties and the catalytic performances over these LaMnO 3 perovskite oxides.

Jun 22, 2018 · X-ray diffraction (XRD) patterns were recorded using a Bruker AXS D8 Advance diffractometer with a θ-θ configuration, using Cu Kα radiation (λ=0.154 nm). Experiments were run between 10 and 90 degrees, using a step size of 0.02 degrees.

Nov 1, 2014 · Visible-light sensitive LaMnO3 nanoparticles were synthesized via sol–gel process. Structural and optical properties of photocatalysts have been investigated. The photocatalytic activity was evaluated by the degradation of methyl orange as a model of pollutant.

Mar 4, 2025 · The as synthesized LaMnO3, rGO and LaMnO3/rGO (25–75%) composite materials are well characterized by the X-ray diffraction (XRD) and Fourier Transform Infra-Red (FTIR) spectroscopic techniques. The textural morphology of the materials is ascertained by Scanning Electron Microscopy (SEM).
