Abstract: The porous structure SnFe 3 N@carbon materials (SnFe 3 N@C) and the fibrous structure SnFe 3 N@carbon materials (SnFe 3 N@CNFs) were synthesized by the simple sintering method and the electrospinning-sintering method using polyacrylonitrile and dicyandiamide as carbon and nitrogen sources. The XRD results demonstrates that the various structures of the SnFe 3 N@carbon materials are well crystallized, and TG analysis reveals that all samples contain approximately 60 wt% carbon, providing insights into the composition and the percentage of organic matter present. Raman spectroscopy and X-ray photoelectron spectroscopy further verified the XRD results, and no impurity phases were formed in the prepared products. VSM measurements revealed that the prepared two different structural SnFe 3 N@carbon materials exhibit superparamagnetic properties. • The porous structural SnFe 3 N@C and the fibrous structural SnFe 3 N@CNFs were successfully synthesized. • Various structures of the SnFe 3 N@carbon materials are well crystallized, and all of them have carbon contents of ∼60 wt%. • VSM measurements revealed that the prepared two different SnFe 3 N@carbon materials exhibit superparamagnetic properties.
