Synthesis and characterization of CdS/UiO-66/Ag3PO4 nanocomposite for photocatalytic degradation of methyl orange under visible light irradiation

Single, binary and ternary nanomaterials were synthesized by precipitation, solvothermal, simple solution impregnation methods to serve as photocatalysts. The crystal structure, morphology, band gap energy, functional groups optical properties of these materials characterized XRD, SEM-EDX, UV-Vis, FTIR, PL instrumental techniques, respectively. Photocatalaytic degradation performances all the as-synthesized photocatalysts investigated under visible light irradiation using MO a model organic pollutant. photocatalytic evaluated on aqueous pollutant dye well real sewage sample collected from Bahir Dar Textile Share Company. Results suggested that optimized nanocomposite photocatalyst exhibited relatively higher efficiency towards photodegradation both methyl orange (MO) (90%) (71.2%). effect operational parameters such pH (4), initial concentration (10 mg/L) load (0.2 g/L) in CdS/UiO-66/Ag3PO4 (R4) nanocomposite.
