Abstract

Co-substituted manganese oxide nanosheets, (Mn 1-xCo x)O 2 have been synthesized in the form of a colloidal suspension via a simple one-pot method. Substitution effects on the structural, optical absorption, and magnetic properties are investigated for the nanosheets and their lamellar aggregates. The composition of the (Mn 1-xCo x)O 2 nanosheets can be controlled continuously by adjusting the molar ratio of the starting materials. The solubility limit is x ∼ 0.20 based on the cell volume. In the 0.00 ≤ x ≤ 0.20 range, the band gap energy, magnetic moment, and Weiss temperature change systematically with x. The charge density of the (Mn,Co)O 2 layer is independent of x (i.e., [(Mn,Co)O 2] 0.2-) and the cobalt ions are trivalent in low-spin state. © 2012 Elsevier Ltd. All rights reserved.
