Overcoming Ion Transport Barrier by Plasma Heterointerface Engineering: Epitaxial Titanium Carbonitride on Nitrogen‐Doped TiO₂for High‐Performance Sodium‐Ion Batteries

Abstract

the electrolyte. The mass of the material loading on an electrode was obtained by weighing N electrodes, subtracting the mass of N pieces of current collectors, and then divided by N. The mass of active material on an electrode = the material loading on an electrode × 0.8. The specific capacity was the measured capacity divided by mass of active material on an electrode. EIS (frequency ≈10 −3 -10 6 Hz) and CV (scan rate 0.2-20 mV s −1 ) were performed on a CHI660E electrochemistry workstation. Charge-discharge tests were carried out in a voltage range of 0.01 to 3 V versus Na/Na + with a LAND battery tester (Wuhan, China).Research data are not shared.

High-Efficacy Hierarchical Dy2O3/TiO2 Nanoflower toward Wastewater Reclamation: A Combined Photoelectrochemical and Photocatalytic Strategy

“…These peaks can be typically attributed to Ti 2p 1/2 and 2p 3/2 levels of Ti(IV) cations. 44 The XPS spectrum of O 1s for Dy 2 O 3 /TNF showed a peak at 529.6 eV attributed to the lattice oxygen peak in TiO 2 and matching the presence of a surface hydroxyl peak on the FT-IR analysis. The high-resolution XPS for Dy 2 O 3 exhibited two peaks at 152.8 and 156.7 eV attributed to Dy 4d 3/2 and Dy 4d 5/2 , respectively.…”

“…The XPS data for high-resolution Ti 2p spectra containing signals at 458.2 and 463.9 eV are in an area ratio of 2:1, respectively. These peaks can be typically attributed to Ti 2p 1/2 and 2p 3/2 levels of Ti­(IV) cations . The XPS spectrum of O 1s for Dy 2 O 3 /TNF showed a peak at 529.6 eV attributed to the lattice oxygen peak in TiO 2 and matching the presence of a surface hydroxyl peak on the FT-IR analysis.…”

Thermodynamic Transformation of Crystalline Organic Hybrid Iron Selenide to FexSey@CN Microrods for Sodium Ion Storage

“…The C 1s XPS spectra of FeSe 2 @CN-420, Fe 3 Se 4 @CN-500, and Fe 7 Se 8 @CN-700 contain two peaks at 284.1 and 285.5 eV, which are originated from the sp 2 C�C and sp 3 C−C bonding, respectively (Figure 3b). 49,50 In addition, the high proportion of sp 2 C�C bonding suggest the presence of graphitic carbon layers in these composites. The N 1s spectra of these composites can be divided into three peaks at ∼398.4, 400.2, and 401.6 eV, which correspond to the pyridinic, pyrrolic, and graphitic nitrogen bonding, respectively (Figure 3c), 51 implying the existence of nitrogen-doped carbon layers in the Fe x Se y @CN composites.…”

Interface Density Engineering on Heterogeneous Molybdenum Dichalcogenides Enabling Highly Efficient Hydrogen Evolution Catalysis and Sodium Ion Storage

“…[11,24] The formation of heterointerfaces is also reported to enhance the performances of sodium ion storage greatly. [16,21,[25][26][27][28] "Ion reservoirs" were formed at the interfaces of Fe 1-x S/MoS 2 heterostructures with reduced Na + diffusion barrier, thus achieving excellent rate capability for SIB. [29] Besides, walnut-like MoS 2 @SnS heterostructures afforded superior SIB performances to original MoS 2 because the built-in electric field at the interfaces greatly enhanced charge transfer and Na + diffusion kinetics.…”
