Coal tar pitch-based carbon composited Sb2Se3 microrod anode toward superior sodium storage performance

Approaching high-performance lithium storage materials of CoNiO2 microspheres wrapped coal tar pitch-derived porous carbon

“…2a, the peak at around 1385 cm −1 represents the defects in the lattice of carbon atoms (D peak), and the peak at 1584 cm −1 signifies the in-plane stretching vibrations in the sp 2 hybridization of carbon atoms (G peak), which demonstrates the existence of carbon. 34,35 The intensity ratio ( I D / I G ) indicates the high graphitization degree in the CNO@CTP10 material, which further suggests that the CTP is graphitized carbon with excellent conductivity. To study the elemental composition and the valence states of the electrode material, the XPS spectra of the CNO@CTP10 composite are displayed in Fig.…”

Cation Exchange-Assisted Hot Injection for PbSe Nanocrystalline Structures Anchored to Sb2S3: Constructing a Deeply Buried Back Interface for Highly Efficient Solar Cells

“…In the survey spectra of the PbSe-modified Sb 2 S 3 film, the obvious Pb element signal can be observed (Figure S22). As illustrated in Figure S23, the peaks at 137.87 and 142.79 eV belong to the binding energies of Pb 4f 7/2 and Pb 4f 5/2 , respectively, representing Pb–Se bond. , The binding energies of the control-Sb 2 S 3 film for Sb 3d 5/2 and Sb 3d 3/2 components are 529.36 and 538.71 eV, respectively. , For the PbSe-modified Sb 2 S 3 film, the peaks located around 529.41 and 529.74 eV are assigned to Sb 3d 5/2 and Sb 3d 3/2 , with a little shift to the higher binding energy. The occurrence of the cation exchange between Pb ions and Sb 2 Se 3 may be responsible for this.…”
