| description | In this work, tungsten oxide crystals (WO3), with different sizes and morphologies were prepared using the reflux condensation method. Tungsten oxide crystals were characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. Then, the particles were used as a heterogeneous Fenton-like catalyst in the presence of green oxidant H2O2 for Indigo Carmin (IC) dye degradation. The efficiency of the coupling WO3/H2O2 showed at 600 °C, that it was possible to remove about 90% of the initial color of IC after 120 min in a batch reaction at 65 °C. Moreover, the coupling maintained high activity after four continuous cycles when tungsten oxide particles were recorvered. |
