No more XRD peaks are found, showing the purity of zinc-cobalt sul de (ZnCoS). In the case of rGO, a broad peak at 25.4° formed, matching the (002) plane, while a smaller peak occurred at...

Jun 5, 2022 · The same crystal structure of cubic Zn 0.76 Co 0.24 S demonstrated in the XRD patterns of ZnCoS and ZnCoS/C 20, indicates that the enhanced electrochemical performance of ZnCoS/Cs results from the synergistic effect between 3-D networks C and ZnCoS nanodendritics.

Oct 15, 2019 · XRD patterns of the prepared ZnCoS materials. The interplanar distance d of diffraction peaks 2θ at values of about 28.6°, 47.8° and 56.7° corresponds to ∼0.30, 0.19 and 0.16 nm, respectively.

Sep 27, 2024 · We synthesized a novel electrocatalyst of copper-doped zinc cobalt sulfide nanosheets (Cu-ZnCoS/NF) via a hexamethylenetetramine-assisted hydrothermal process.

Nov 30, 2023 · X-Ray diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FESEM), and high-resolution transmission electron microscopy (TEM) characterizations were used to test ZCS and rZCS NPs.

Sep 12, 2023 · XRD and XPS revealed the physical and chemical structure of the ZnCoS materials. SEM and TEM observations showed that the microstructure of ZnCoS transformed from one-dimensional wires to two-dimensional sheets with increasing amounts of ethanol.

Jun 23, 2022 · Distinctive formation of ZnCoS-reduced graphene oxide (rGO) hollow microsphere flowers (HMFs) undergoes three stages with aggregation–dissolution–incubation, aiming to achieve excellent electrochemical performance for Li …

Sep 12, 2023 · XRD and XPS revealed the physical and chemical structure of the ZnCoS materials. SEM and TEM observations showed that the microstructure of ZnCoS transformed from one-dimensional wires to two-dimensional sheets with increasing amounts of ethanol.

In this work, we develop a high energy density hierarchical ZnCo2S4/ZnCo2O4 electrode material with flower-like structure directly anchored on nickel foam by hydrothermal and ion exchange...

Mar 1, 2022 · In this work, a titanium-doped zinc–cobalt sulfide hollow superstructure (Ti–ZnCoS HSS) is rationally designed as an efficient electrocatalyst for H 2 O 2 electrosynthesis.
