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 axial direction).
