Studies on Fe-modified nanostructured trititanates

▶ 1D nanostructured titanate easily exchanged with Fe3+ following the Langmuir adsorption model. ▶ Iron caused interlayer shrinkage and reduced bandgap energy. ▶ Iron also found in a lower oxidation state Fe2+. ▶ Fe-modified trititanate nanostructure (Fe/TTNS) is stable up to 400 °C and eventually transforms into rutile and pseudobrookite.
