Surface Chemical Analysis and Electrokinetic Properties of Synthetic Spherical Mixed Zinc–Cadmium Sulfides

Cd1−xZnxS solid solutions supported on ordered mesoporous silica (SBA-15): Structural features and photocatalytic activity under visible light

“…The Si 2p core level peak is characteristic of the presence of oxides Si(IV) [49] whereas the O 1s peak is assigned to oxygen in SieOeSi. Both Cd 0.80 Zn 0.20 S/S15 and Cd 0.95 Zn 0.05 S/S15 photocatalysts shows the Zn 2p 3/2 peak at BE's about 1021.7 eV which is characteristic of ZnS [50]. For all catalysts, the binding energy for S 2p is about 161.7 AE 0.1 eV that agrees with the reported value of S with the valence state À2 [51].…”

Aqueous Phase Synthesis and Enhanced Field Emission Properties of ZnO-Sulfide Heterojunction Nanowires

“…The 3d 5/2 and 3d 3/2 spin-orbit splitting of the Cd 3d level occurs at the binding energies of 405.4 and 412.1 eV in the ZnO-CdS, respectively. The Cd 3d 5/2 peak at the binding energy of 405.4 eV corresponds to Cd 2+ combined with S 2− 33 34 . Figure 4d shows the high resolution XPS spectra of S 2p peaks.…”

Effect of NOM on copper sulfide nanoparticle growth, stability, and oxidative dissolution

“…This is consistent with a reported point of zero charge (PZC) for Cu x S ranging between pH 1 and 3. [68][69][70][71][72] Even a decrease in pH to 6 did not cause notable aggregation and only occasional aggregates ∼100 nm were observed in an otherwise welldispersed suspension after 24 h (Fig. S10 †).…”
