Van der Waals Black Phosphorus/Bi10O6S9 Heterojunction Harvesting Ambient Electric Field Energy for Enhanced Photoelectrochemical Sense

“…The chemical states of the WBB composite are also analyzed by XPS analysis in Figure 3c−h, where all peak positions are calibrated at 284.6 eV with C 1s. 79 In Figure S4 in the Supporting Information, the survey spectrum shows the co-presence of O, C, S, Bi, P, and W elements, which is consistent with Figure 2h−l. As shown in Figure 3c, the three strong peaks at 284.6, 285.93, and 287.92 eV correspond to C−C, C−O, and C�O bonds, respectively.…”

“…The peak is relatively weak because of low crystallinity, a small lamellar size, and scarcity of content of BP, as shown in Table S1 and Figure c. The chemical states of the WBB composite are also analyzed by XPS analysis in Figure c–h, where all peak positions are calibrated at 284.6 eV with C 1s . In Figure S4 in the Supporting Information, the survey spectrum shows the co-presence of O, C, S, Bi, P, and W elements, which is consistent with Figure h–l.…”

“…80 Furthermore, in the Bi 4f spectra of the sample in Figure 3e, the main deconvoluted peaks at 158.68 and 163.98 eV correspond to the binding energies of Bi 4f 7/2 and Bi 4f 5/2 , respectively. 79,81 The two main peaks centered at 159.85 and 165.32 eV are slightly shifted to low binding energy corresponding to the low-valence Bi ions (Bi (3−x)+ ) due to the breaking of the Bi−O bond and forming oxygen vacancies during the reduction process. In Figure 3f, the 34.98 and 37.12 eV peaks can be attributed to W 4f 7/2 and W 4f 5/2 , respectively.…”

“…2c), which is consistent with the literature. 26 The Raman spectrum was further determined to evidence BiCoO-NA/NF and CoO-NA/NF. In the Raman spectra (Fig.…”

Kinetic Comparison of Photocatalysis with the Photo-Fenton Process on the Removal of Tetracycline Using Bismuth-Modified Lanthanum Orthoferrite Nanostructures

“…Figure g illustrates the deconvoluted XPS spectra of La 3d with two spin–orbit couple-derived peaks at 833.58 and 850.45 eV (spin–orbit splitting of 16.87 eV) corresponding to La 3d 5/2 and La 3d 3/2 . In addition, two shakeup satellite peaks were also found at 835.71 and 854.24 eV, which corresponds to the electron transfer to an empty 4f orbital (3d 9 4f 0 ) from the O 2p orbital . The doping caused a change in the chemical state of La 3d with a redshift in peak position to lower binding energies and an increase in the intensity of satellite peaks.…”
