摘要

A cost-effective and efficient hydrothermal approach was employed to synthesize pure MOF-5 and Ag-doped MOF-5 nanostructures at various concentrations. XRD, Raman, UV–Vis, XPS, and I–V characteristics measurements were conducted to evaluate crystallinity, bandgap, chemical composition and electrical properties, respectively. The spectrophotometric technique was used to measure the photocatalytic activity of the prepared nanomaterials. Additionally, under visible light irradiation, the photocatalytic removal of methylene blue (MB) dye from its aqueous solution utilizing MOF-5 and different concentration of Ag-doped MOF-5 were investigated. Under optimal conditions, the results of the present research indicated that the maximum degradation efficiency reached 98.5% for 4% Ag-doped MOF-5, which outperformed than the other samples. This results that the MOF-5 and 4% Ag-doped MOF-5 is a promising and superior photocatalyst compared for degradation of the methylene blue pollutant.
