摘要:This paper presents a study on the doping TiO2 with Cu referred as TiO2-Cu, to enhance its visible light photocatalysis process for amoxicillin degradation. The doping was carried out by photodeposition of Cu2+ into TiO2 structure. The effect of the amount of Cu doped on TiO2 towards the characters and photoactivity was evaluated. The doped TiO2 resulted was characterized by XRD and UV-Vis DR spectrophotometry methods. The activity of the photocatalyst was examined for degradation of amoxicillin in water with the presence of visible light. The results of the research, attributed that Cu doping on TiO2 could uniquely improve the crystallinity of TiO2, shifted the light absorption into visible region, and enhanced the photocatalytic activity on the amoxicillin degradation under visible light. The maximum shift and the highest enhancement of the activity were exhibited by Cu doped on TiO2 as much as 4.56 mg g-1. It was also found that the highest photodegradation (about 90%) of 10 mg L-1 amoxicillin by TiO2-Cu with 4.56 mg g-1 of Cu doped, was achieved by 0.40 g L-1 of the photocatalyst dose, in 24 h, and at pH 6.
