Surfactant-Free Microwave-Assisted Synthesis of Fe-Doped ZnO Nanostars as Photocatalyst for Degradation of Tropaeolin O in Water under Visible Light
Figure 12
The degradation of Tropaeolin O (a) with presence of Fe-doped ZnO nanostars, (b) with presence of undoped ZnO, (c) without any photocatalysts, and (d) without irradiation. Reaction conditions: catalyst loading (30 mg), temperature (60°C), light distance (0 cm), initial pH (pH = 9), and irradiation time (3 h).
