AI Article Synopsis
Electrospinning was utilized to create carbon nanofibers doped with cobalt-chromium carbide nanoparticles, achieved using cobalt acetate and chromium acetate mixed with poly(vinyl alcohol).
The carbonization process occurred at a low temperature of 850 °C for 3 hours under an argon atmosphere, facilitated by cobalt's role as an activator.
Characterization techniques such as FE-SEM, XRD, and TEM revealed the successful formation of pure cobalt, Cr7C3 nanoparticles, and crystalline carbon nanofibers, suggesting potential for developing various metal-carbide-carbon nanofibers efficiently.
Article Abstract
Electrospinning has been used to synthesize cobalt-chromium carbide nanoparticles (NPs)-doped carbon nanofibers (CNFs) (Composite). Electrospun mat comprising of cobalt acetate, chromium acetate and poly(vinyl alcohol) (PVA) has been carbonized at low temperature (850 °C) for 3 h under argon atmosphere to produce the introduced composite. The process was achieved at low temperature due to the presence of cobalt as an activator. Field emission scanning electron microscope (FE-SEM), X-ray diffractometry (XRD), and transmission electron microscopy (TEM) equipped with EDX techniques were used to determine the products characteristics. The results indicated the formation of pure cobalt (Co), Cr7C3 NPs and crystalline CNFs. The Co and Cr7C3 NPs were covered with CNFs. Overall, the proposed NFs open new avenue to prepare different metals-metal carbides-carbon NFs at low temperature and short reaction time.
