title: α-Fe2 O3 nanodisks: layered structure, growth mechanism, and enhanced photocatalytic property.
abstract: Layered structure: α-Fe2 O3 nanodisks with a layered structure assembled from nanoplates were produced by a hydrothermal method. The simple, low-cost method used silicate anions as capping ligands, which selectively adsorbed onto the {0001} facet of α-Fe2 O3 and terminated the growth along the [0001] direction, leading to platelike building units. The layered structure led to significantly enhanced absorption of visible light, compared with single-layer α-Fe2 O3 , and excellent photocatalytic abilities.
