Synthesis and characterization of TiO2/Fe2O3 core-shell nanocomposition film and their photoelectrochemical property

► TiO2/Fe2O3 core-shell nanocomposition film has been fabricated via two-steps method. Such 1D nanostructured materials with better property have been uncommonly previously. ► UV-vis absorption property is induces the shift of the absorption edge into the visible-light range. ► The TiO2 NRs modified by Fe2O3 show higher photocurrent value than those of unmodified TiO2 NRs and other conditions.
