Hydrothermal synthesis of a concentrated and stable dispersion of TiO2 nanoparticles

► Two-step, low temperature hydrothermal method. ► Deagglomeration and stabilization of 6 nm nanoseeds via hydrothermal treatment. ► Stable dispersion of anatase TiO2 nanoparticles with a zeta potential of −51 mV and content of 10 wt.%. ► Attractive as coating solution for the deposition of different morphologies of TiO2.
