“…These findings demonstrated that the Co/C catalysts had abundant oxygen-containing and carbon-containing functional groups. The Co–O peaks near 660 cm −1 and 570 cm −1 indicated that the Co/C catalysts contained CoO, 32 which was consistent with the XRD results.…”

“…On the other hand, the morphology, surface areas, and structure of the nano-Co 3 O 4 catalysts could also influence the degradation performance to a large extent . Accordingly, the Co 3 O 4 , hollow Co 3 O 4 /N–carbon, the Co 3 O 4 -based composites such as Co 3 O 4 –Bi 2 O 3 , Co 3 O 4 /MXene, Co 3 O 4 /N–C@SiO 2 , and so on were well developed to activate the oxidants for the degradation of BPA. ,− Additionally, in spite of cobalt-based nanomaterials, other nanomaterials such as Fe 2 O 3 /MnO 2 and nanocarbons could also be used to activate the potassium persulfate (PS) …”

The zeolitic imidazolate framework (ZIF)-67 microcrystal was employed as a precursor to synthesize the hollow ZIF-8/ZIF-67 composite via the epitaxial growth of ZIF-8 on ZIF-67, in situ self-sacrifice, and excavation of ZIF-67. The hollow ZIF-8/ZIF-67 composite was successfully transformed to the ZnO–Co3O4/N–C cage by thermal treatment, which was further used as the catalyst for the oxidative degradation of bisphenol A (BPA) in the presence of potassium persulfate (PS). In comparison with the Co3O4/N–C and Co3O4 obtained from pure ZIF-67 and cobalt nitrate, the ZnO–Co3O4/N–C cage demonstrated a more than four fold-higher activity and robust reusability. Based on structural analysis, the enhanced catalytic performance could be ascribed to the small, highly dispersed cobalt oxide particles, the hollow structure that facilitated the transportation of the molecules, and the synergistic effect between cobalt oxide and nitrogen-doped carbon in the composite. Besides, the effect of dosage of PS, BPA, and the co-existing components such as chloride ion, methanol, and t-butyl alcohol was carefully investigated to propose the possible mechanism. This study would give new insights into the design of functional composite materials from metal organic frameworks and the development of their application in environmental pollution disposal.

“…This shows that the NiCo2O4 material is indicated in the synthesis of nanocomposites, at that wavenumber a very sharp peak occurs. At the peak of 532 cm -1 induced by Co-N stretching, indicating the coordination of Co and N in Ni-Co, this study was carried out by Wang et al in 2021 [31]. There is a Fe-O functional group in the wavenumber of 536 cm -1 [32][33][34].…”

Fe3O4/NiCo2O4 nanocomposites were successfully fabricated using the coprecipitation method. The fabrication of Fe3O4/NiCo2O4 nanocomposites were carried out by varying the mass percentage of NiCo2O4 with a composition of 0%, 15%, 30%, 45%, and 100% of the mass of Fe3O4. The characterization of the functional groups of Fe3O4/NiCo2O4 nanocomposites was carried out using the FTIR instrument which showed the functional group bonds of the sample corresponding to the constituent atoms. The characterization of the crystal structure of Fe3O4/NiCo2O4 nanocomposites was carried out using an XRD instrument which showed the appearance of characteristic peaks of the Fe3O4 and the NiCo2O4 phases in the X-ray diffraction patterns. The surface morphology of the Fe3O4/NiCo2O4 nanocomposites was characterized using the SEM instrument which produces an image of the surface morphology of the sample. Potential applications of Fe3O4/NiCo2O4 as photodegradation material for methylene blue (MB) were characterized using a UV-Vis instrument and showed that the Fe3O4/NiCo2O4 nanocomposites can be used for water purification with a degradation percentage of 11.99%. The highest absorbance values of the Fe3O4/NiCo2O4 nanocomposites with UV irradiation for interval of 60, 120, and 180 minutes located at wavelength of 613 and 663 nm.
