Cu doped ZnO microballs as effective sunlight driven photocatalyst

Cu doped ZnO microballs were synthesized via oxalate assisted sonochemical route by using Zn(NO3)2 and Cu(NO3)2 as precursors. Field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) analysis results demonstrate several nanosheets-like structures assembled to form microballs...

Summary:Cu doped ZnO microballs were synthesized via oxalate assisted sonochemical route by using Zn(NO3)2 and Cu(NO3)2 as precursors. Field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD) analysis results demonstrate several nanosheets-like structures assembled to form microballs of 2–4μm diameters. Room-temperature photoluminescence spectra (PL) show near band emission centered at ~390nm. Absorbance spectra reveal red shift towards UV region on incorporation of Cu in ZnO. The as-synthesized products with extended light absorption exhibits excellent sunlight driven photodegradation ability towards Methylene blue (MB) and Rhodamine B (RhB) dyes.
