Bismuth oxyhalide (BiOCl) has been demonstrated to be a new and excellent photocatalyst. To further improve its photocatalytic activity, we prepared BiOCl samples doped with different amount of Er3+ and/or Yb3+ ions by a simple hydrothermal method. These doped BiOCl samples exhibit sheet-shaped structure, and their thickness goes down from ~140nm to ~80nm with the increase of the Ln doping amount...
Bi2WO6 has attracted much attention as a visible-light-driven photocatalyst, but its photocatalytic activity should be further improved for future practical application. Herein, we prepared Yb3+/Er3+ co-doped Bi2WO6 (Yb3+/Er3+-Bi2WO6) by a facile hydrothermal route followed by a calcination process. Yb3+/Er3+-Bi2WO6 sample consisted of two dimensional nanosheets with the thickness of about 50nm and...
