Abstract:

Mesoporous carbon with monolithic structures were prepared using abandoned crab shells as a template. And then Fe3O4 nanoparticles inside those monolithic mesopores were synthesized by the confined in-situ synthetic strategy. The properties and structure of Fe3O4 nanoparticles on nesoporous narbon were characterized by scanning electronic microscopy(SEM), transmission electron microscope(TEM) and X-ray diffraction(XRD). The results show that the pores have a monolithic structure. The diameters of the pores are ca. 40~50 nm and their lengths are ca. 50 μm to 200 μm. The nanoparticles are proven to be Fe3O4 with 10 nm in diameter, which have good size monodispersity and are evenly distributed inside the pores. This method features simple and environmental benignity.
