Abstract: Disclosed are layered ferric rust and iron hydroxide nanoparticles including the same, wherein the layered ferric rust has a novel crystal structure that satisfies conditions (a) to (c) below:

(a) a crystal system belongs to a monoclinic system;
(b) a space group belongs to Pn (No. 7); and
(c) unit cell parameters are a = 3.854 ± 0.002 Å, b = 11.491 ± 0.007 Å, c = 9.818 ± 0.004 Å, and β = 88.47 ± 0.005° (b is the distance between layers in the [010] axial direction).
