Jun 1, 2021 · Herein, ultrathin ZnIn 2 S 4 (ZIS) nanosheets with oxygen doping were synthesized by a one-pot solvothermal method. XRD, XPS and Raman spectral measurements support the presence of lattice oxygen in the oxygen-doped ZIS (O–ZIS) sample.

Jan 6, 2024 · S 2p X-ray photoelectron spectroscopy (XPS) exhibited higher energy shifts in D-ZIS, with additional peaks assigned to the S-S bond (S 2 2−) at 164.4 and 165.3 eV (Fig. 2a) 26.

Mar 1, 2022 · Mechanism analysis and DFT calculations reveal that the interfacial chemical bond contributes to the intense internal electric field (IEF) in CdSe/S L -ZIS/MoSe 2, and finally lead to the direct Z-scheme-dominated and II-scheme-assisted charge transfer mechanism.

Mar 11, 2022 · Here we have conducted a photochemical reaction to stabilize ultralow Pt co-catalysts (0.26 wt%) onto the basal plane of hexagonal ZnIn 2 S 4 nanosheets (Pt SS -ZIS) to form a Pt-S 3 protrusion...

In this work, the sulfur vacancies were successfully introduced into the ZnIn2S4 (ZIS) lattice through two facile approaches, plasma etching and annealing, for enhancing the photocatalytic...

Jul 5, 2021 · Systematic investigations reveal that Mo-S bond and internal electric field induce the Z-scheme charge transfer mechanism as confirmed by the surface photovoltage spectra, DMPO spin-trapping...

XPS spectra of pristine ZIS and H-ZIS: (A) O 1s, (B) C 1s, and(C) N 1s To further investigate the influence of hydrogenation process on the chemical composition of ZIS, the high-resolution XPS spectra of O 1s, C 1s and N 1s were also examined, as shown in Fig. S3. The peaks corresponding to O 1s and C 1s were

Aug 22, 2023 · The microstructures, chemical compositions, and crystalline structures of CNNs and different ZIS@CNNs composites were identified using scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD).

Jan 9, 2022 · Herein, we demonstrate for the first time the rational design and construction of Ce-doped ZIS tetrakaidecahedron hollow nanocages photocatalysts via one-step hydrothermal method with an ordered large-pore tetrakaidecahedron Ce-MOFs as …

Nov 11, 2022 · ZIS, Sv-ZIS and Mo-Sv-ZIS are investigated further by XPS for chemical states and apparent chemical compositions. Figure S3 displays the full spectrum of ZIS, Sv-ZIS and Mo-Sv-ZIS containing the typical peaks of Zn 2 p, In 3 d, S 2 p and Mo 3 d, which is consistent with the EDS’ results.
