Witryna4 cze 2024 · Ferrite nano-hollow spheres (NHS) are of great significance to improve electromagnetic (EM) wave absorption performance. Herein, the deposition of dielectric SiO 2 and ferrimagnetic CoFe 2 O 4 (CFO) layers on MnFe 2 O 4 (MnFO) NHS are found as an effective strategy to enhance EM wave attenuation. Witryna11 sty 2024 · After 6 h pyrolysis, no evident long carbon nano-hollow-sphere chains (CNHSCs) are observed. However, when the pyrolysis temperature was raised up to 800°C for 5 min, some carbon nano-hollow-spheres and one enclosing Co NPs appear (Figure 2C). It seems that the above N,S co-doped carbon species become to cover … WitrynaThe hollow sphere structure provides a large accessible surface area for charge transfer and enhances photo-absorption properties. Particularly, the doped P can regulate the energy band structure with stronger reducibility for O 2 activation and accelerate photo-generated carrier separation. thekiwicoder tps github
