Haunted with morphology: α-Fe2O3 with different morphologies is synthesised by using an ionic liquid-mediated hydrothermal method. Although α-Fe2O3 with various morphologies possesses comparable reduction properties, large differences in oxygen mobility are observed. Oxygen mobility is favoured by the increase in surface area and decrease in crystal size, which makes the porous nanorod morphology the more active material for oxygen exchange and enables us to design a highly active oxidation catalyst.
