Photocatalytic Activity of CdSe/K₂La₂Ti₃O₁₀ for Rhodamine B Degradation under Visible Light Illumination

Abstract:

The composite CdSe/K₂La₂Ti₃O₁₀ photocatalyst was synthesized via a precipitation method. The structure of the photocatalyst was determined by powder X-ray diffraction. The photocatalytic properties for organic matter degradation of the photocatalyst were examined under visible light irradiation, using rhodamine B as the goal degradation content and halogen lamp (λ > 420 nm) for the light source. The results show that when the pH of the rhodanmine B at 7, initial concentration of 10 mg/L and every 250 mL solution catalyst dosage is 0.25 g, and the degradation rate of rhodamine B for 4 hours was 50%.
