| Abstract: | The microstructure and electronic properties of the surface of TiO 2 particles before and after modification with HCl and HClO 4 were studied by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS). After modification with strong acid, the reduction of the density of surface state of TiO 2 led to negative shifting of the conduction band, increasing the surface band gap, and improving the photocatalytic activity of TiO 2. |
