Surfactant-Free Microwave-Assisted Synthesis of Fe-Doped ZnO Nanostars as Photocatalyst for Degradation of Tropaeolin O in Water under Visible Light

Figure 13

Reusability study on the Fe-doped ZnO nanostar photocatalyst for the degradation of Tropaeolin O under optimal reaction conditions. Reaction conditions: catalyst loading (30 mg), temperature (60°C), light distance (0 cm), initial pH (pH = 9), and irradiation time (3 h).
