  • Iron doped titanium dioxide nanocrystals and their use as photocatalysts
    Patent number: 10413888
    Abstract: A method of making a visible light photo-catalyst is provided, the method comprising doping a titanium dioxide nanocrystal with iron to provide an iron-doped nanocrystal, washing the iron-doped nanocrystal with an acid to produce an acid-washed iron-doped titanium dioxide nanocrystal and rinsing the acid-washed iron-doped titanium dioxide nanocrystal to remove a residual of the acid, thereby providing a visible light photo-catalyst. The photo-catalyst is also provided, as are methods of using the photo-catalyst in remediation.
    Type: Grant
