XRD pattern of NaO2 is shown in Figure 1. The peaks (200), (220), (311) and (222) appear in XRD accurately index to NaO2 according to JCPDS reference card No. 01-077-0207, which confirms...

May 15, 2020 · We have investigated the high-pressure behavior of sodium oxide (Na 2 O) up to 30 GPa by synchrotron angle-dispersive powder X-ray diffraction in a diamond anvil cell at room temperature.

In this study, the investigation of materials with corrosion resistance was carried out to prevent side reactions caused by sodium oxide (Na2O) in the Na-redox thermochemical water splitting cycle,...

Na2O is Fluorite structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Na1+ is bonded to four equivalent O2- atoms to form a mixture of edge and corner-sharing NaO4 tetrahedra. All Na–O bond lengths are 2.42 Å. O2- is bonded in a body-centered cubic geometry to eight equivalent Na1+ atoms.

Jan 1, 2023 · Use in-situ XRD to observe the growth and decomposition pattern of NaO 2. Regulate the morphology of NaO 2 by tuning the glyme solvent ratio (DME: TEGDME). Propose a new descriptor α to descript the mechanism behind the morphological evolution of NaO 2.

In the present work, we successfully prepared sodium superoxide (NaO2) doped vanadium phosphate borate glasses using normal melt quenching technique of composition 60V2O5–5P2O5– (35-x)...

Figure S 1 – XRD diffraction patterns of commercial sodium oxide (Na 2 O) and sodium peroxide (Na 2 O 2) powders, as well as of thermochemically synthesized sodium superoxide (NaO 2) prepared at the Max-Planck-Institute for Solid State Research, Stuttgart, Germany.

We have investigated the high-pressure behavior of sodium oxide (Na2O) up to 30 GPa by synchrotron angle-dispersive powder X-ray diffraction in a diamond anvil cell at room temperature.

Jul 31, 2024 · Here, a phosphorous and nitrogen dual-doped carbon (PNDC) based cathode is synthesized to increase the electrocatalytic activity and to stabilize the NaO2 superoxide nanoparticle discharge products, leading to enhanced cycling stability when compared to the nitrogen-doped carbon (NDC).

In this study, we used in operando synchrotron radiation powder X-ray diffraction (SR-PXD) to (i) quantitatively track the formation of NaO 2 in Na–O 2 cells and (ii) measure how the growth of crystalline NaO 2 is influenced by the choice of electrolyte salt.
