Figure 5: Kinetics of phenol degradation for samples AmT_8%, AmT_10%, WO3_10%, and WO3_8% under UV-Vis light. Experimental conditions: light source: Xe lamp, irradiation flux 24 mW/cm2, phenol initial concentration: 0.2 mM, (TiO2) = 0.05 g, and °C. The effect of calcination temperature for the most active samples WO3_8%, WO3_5%, and AmT_10% (b).
