SYNTHESIS AND PHYSICO-CHEMICALCHARACTERIZATION OF NiZnAl-LDH/PVA ANDNiZnS2/NiZnAl-LDH/PVA NANOCOMPOSITES

Nickel zinc aluminum layered double hydroxides (NiZnAl-LDH) were synthesized by co-precipitation and co-formation methods using urea in polyvinyl alcohol (PVA) solution.On the obtained nanocomposites nickel-zinc sulfide (NixZn1-xS; x=0.25, 0.5, 0.75) nanoparticles were synthesized by successive ionic layer adsorption and reaction (SILAR) method at room temperature (25C).The photocatalytic degradation of Ponceau 4R (P4R) and Rhodamine 6G (R6G) with obtained LDH and sulphide nonmaterials were studied under visible light source (150W).NiZnAl-LDH and NixZn1-xS/NiZnAl-LDH (x=0.25, 0.5, 0.75) nanocomposites were characterized by Ultraviolet (UV) spectratrometer, X-ray diffractometer (XRD), Energydispersive X-ray (EDX), Fourier transform infrared (FTIR) spectratrometer and Scanning electron microscopy (SEM).
