Photocatalytic efficiency of reusable ZnO thin films deposited by sputtering technique

- Decolorization of Orange G dye using highly c-axis-oriented ZnO thin films.
- The flake-shaped film shows superior and stable photoactivity at a wide range of pH.
- The highest photodecolorization was achieved at pH of 7.
- The exposure of (101) and (100) facets enhanced the photoactivity.
- ZnO thin films exhibit a promising performance as recyclable photocatalysts.
