“…CeO 2 is a very active rare earth oxide, and it can coordinate to electron-donating groups such as carboxylates, amides, imidazoles, indoles. 59,60 CeO 2 NPs create pits in the walls of the bacterial cell leading to the enhanced permeability through the wall causing the bacterial cell death. In general, RSF/CeO 2 NPs hybrid fibers have an excellent antibacterial activity.…”

Regenerated silk fibroin (RSF) fibers have great application prospects in medicine, textiles, optoelectronics, and other fields. However, under the synergistic action of ultraviolet, oxygen, and water, RSF will inevitably become brittle, which will greatly shorten the service life of RSF. Therefore, it is urgent to find some methods to protect RSF from aging damage. Cerium dioxide nanoparticles have a strong ultraviolet absorption and antioxidant capacity and have been used as an anti‐aging component for other biomaterials. Thus, the RSF/CeO2 NPs hybrid fibers were successfully prepared, and a series of artificial aging tests were carried out. Mechanical property is an important index to measure the aging degree. After aging, compared with RSF, the stress of RSF/CeO2 NPs hybrid fibers was increased by 130.47 ± 4.78 MPa, and the strain of RSF/CeO2 NPs hybrid fibers was increased by 69.89% ± 1.37%. The results of Fourier transform infrared spectroscopy, UV–Vis, sodium dodecyl sulfate polyacrylamide gel electrophoresis discussed the protective mechanism of CeO2 NPs, which prevent the transition from β‐sheet to α‐helix/random coil and the disorder of structure. Furthermore, RSF/CeO2 NPs hybrid fibers have an excellent antibacterial activity against Escherichia coli and Staphylococcus aureus bacteria; the antioxidant activity of RSF/CeO2 NPs hybrid fibers is gradually enhanced in the presence of UV‐light.

“…34,35 Because of their compatible band structures, it is therefore reasonable to expect that an interfacial Z-scheme heterojunction between CeO 2 and ZnO would be achieved. [36][37][38] This heterojunction is anticipated to be a highly efficient photocatalyst with effective separation of photoinduced charge carriers and high redox capacity. 39 As per the literature, this is the first study of the green synthesis of CeO 2 @ZnO employed for the removal of ES pesticide and EBT dye.…”
