摘要：
In this work, a novel Ag2S/NH2-UiO-66 (Ag2S/NU-X) p-n structure was constructed by surface precipitation of p type Ag2S on n-type NH2-UiO-66. Ag2S/NU-X was found to degrade 83.5% of tetracycline (TC) in water under visible light irradiation. XRD, SEM, and XPS showed that NH2-UiO-66 and Ag2S were successfully loaded. In addition, the photocatalytic activity of the composites was greatly enhanced, as evidenced by the photo electrochemical measurements. These results confirm the improved performance and suggest a plausible mechanism for the observed enhancement.
