Simple synthesis of lithium-doped sulfated titania nanoparticles and their high visible light photocatalytic activity under negative bias electrostatic field

Abstract

Li-doped TiO₂/SO₄²⁻ nanoparticles were successfully synthesized <italic>via</italic> a simple calcinination process in a vacuum environment using Ti(SO₄)₂ and LiBr as precursors, and were characterised by TEM, XRD, IR, DLS, XPS and UV-vis (DRS).
