An efficient precursor method to porous hematite architectures and their photocatalytic properties

Uniform Fe0.985S crystals with novel structures can be fabricated by tuning the volume ratio of water and ethanol (or glycerol). After calcination at 500 °C, the porous α-Fe2O3 architectures can be produced from as-prepared Fe0.985S samples as an efficient precursor. Furthermore, the porous α-Fe2O3 architectures could maintain the main morphologies of the Fe0.985S precursors. Compared with the α-Fe2O3 powder, the porous α-Fe2O3 architectures show high photocatalytic performance for methyl orange.
