Abstract
FeB(C) nanocapsules were prepared by arc-discharging Fe80B20 alloy in Ar and CH4. X-ray diffraction and transmission electron microscopy analyses showed that the FeB(C) nanocapsules had a core–shell structure with α-Fe and Fe3B as cores and graphite as shells. The formation mechanism of the FeB(C) nanocapsules is discussed. The graphite shells display a strong anti-acid effect. The saturation magnetization at room temperature of the FeB(C) nanocapsules is much higher than that of Fe(B) nanocapsules. The blocking temperature of FeB(C) nanocapsules is above 300 K.
