Herein, we developed a novel anodic electrodeposition route to prepare shape-controlled alpha-FeOOH thin films on indium tin oxide (ITO) substrates in aqueous (NH4)(2)Fe(SO4)(2) solutions. Different morphologies of alpha-FeOOH products, including platelets, rhombohedral rods, square rods, six-fold snowflakes, and hexagonal particles were obtained by controlling the growth rates of various facets of the deposit with appropriate capping agents. Furthermore, we demonstrated that alpha-FeOOH films can be transferred into alpha-Fe2O3 nanostructures with the same morphologies through a thermal annealing process.
