Sb₂O₃ nanoparticles anchored on N-doped graphene nanoribbons as improved anode for sodium-ion batteries

Abstract

A hybrid nanocomposite of Sb2O3 nanoparticles anchored on N-doped graphene nanoribbons is used as anode in SIBs. These hybrid electrodes demonstrate a high charge transfer and improved microstructure, facilitating the Na+ diffusion in the electrode.

CdS-carbon black hybrid nanocomposite buffer layer for antimony sulfide solar cells

“…S2†) also exhibits the peak related to the transverse optical (TO) mode, which has been previously observed in nanocrystalline CdS films. 23 Moreover, the CdS–CB film shows typical Raman peaks corresponding to the D and G band of the carbon materials at 1344 and 1594 cm −1 , 24 similar to those presented in the CB powder spectrum. The peak at ∼150 cm −1 corresponds to the anatase phase of TiO 2 , indicating the TiO 2 /CdS–CB substrates.…”

Synthesis of Sb–pyromellitic acid metal–organic framework material and its sodium storage properties

“…In comparison, Sb-PMA-300 presents an obvious peak at 2q = 28°and two small peaks at 2q = 45.9 and 54.5°, respectively, which can be indexed to crystalline Sb 2 O 3 (PDF# 43-1071). 30 However, the intensity of these peaks is still very weak, indicating that the content of Sb 2 O 3 is very low. FTIR and Raman spectroscopy were also used to characterize Sb-PMA-300.…”

Tailoring Rational Crystal Orientation and Tunable Sulfur Vacancy on Metal‐Sulfides toward Advanced Ultrafast Ion‐Storage Capability

“…The Sb 3d 3/2 and Sb 3d 5/2 characteristic peaks of the other as-prepared samples are located at the similar positions with that of SS/P, except that an distinct characteristic peak of SbOC bonds appears at 532.55 eV in the spectrum of SS/H@C, which confirms the successful construction of interfacial chemical bonds and agrees well with the FT-IR and ESR spectrums. [24] However, SS/C has few SbOC bonds in spite of containing plentiful S-vacancies (Figure S3a, Supporting Information). As depicted in Figure S5a1 (Supporting Information), it is because the carbon of SS/C fails to wrap on Sb 2 S 3 rods but exists in the form of individual carbon spheres, which thereby leads to scarce covalent bonding between Sb 2 S 3 rods and carbon spheres.…”
