From: Novel hollow α-Fe2O3 nanofibers via electrospinning for dye adsorption
M-H curves and the adsorption capacity of MO of hollow α-Fe2O3 nanofibers. Magnetic hysteresis loops of α-Fe2O3 fibers measured at 300 K and the C/C 0 versus time plots for adsorption of MO solution using (a) solid fibers and (b) hollow fibers made of rice-like nanorods; the inset shows the magnetic response of hollow α-Fe2O3 fibers made of rice-like nanorods after adsorption of MO for 15 min.
