Photocatalytic degradation of Methylene Blue using a mixed catalyst and product analysis by LC/MS

We studied the structural and antimicrobial properties of copper oxide nanoparticles (CuO NPs) synthesized by a very simple precipitation technique. Copper (II) acetate was used as a precursor and sodium hydroxide as a reducing agent. X-ray diffraction patter (XRD) pattern showed the crystalline nature of CuO NPs. Field emission scanning electron microscope (FESEM) and field emission transmission electron microscope (FETEM) demonstrated the morphology of CuO NPs. The average diameter of CuO NPs calculated by TEM and XRD was around 23 nm. Energy dispersive X-ray spectroscopy (EDS) spectrum and XRD pattern suggested that prepared CuO NPs were highly pure. CuO NPs showed excellent antimicrobial activity against various bacterial strains (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Enterococcus faecalis, Shigella flexneri, Salmonella typhimurium, Proteus vulgaris, and Staphylococcus aureus). Moreover, E. coli and E. faecalis exhibited the highest sensitivity to CuO NPs while K. pneumonia was the least sensitive. Possible mechanisms of antimicrobial activity of CuO NPs should be further investigated.

Photocatalytic degradation of ciprofloxacin drug in water using ZnO nanoparticles

ZnS nanoparticles were synthesized using a chemical precipitation method and were characterized with FTIR, transmission electron microscope (TEM), X-ray diffraction analysis (XRD) and UV–vis absorption. XRD analysis shows that the diameter of the particles is 1.6 nm. The interaction between ZnS nanoparticles and safranin O (SO) dye was studied with UV–vis absorption as well as fluorescence emission and excitation spectra. The results show fluorescence enhancement from dye molecules with nanoparticles upon excitation at 325 nm. In contrast, the fluorescence of the dye monitored at 520 nm is quenched by ZnS nanoparticles. ZnS nanoparticles were used as a photocatalyst in order to degrade SO dye. A maximum degradation efficiency of 51% of the dye has been achieved in the presence of ZnS as a nanophotocatalyst at pH 7. Photodegradation of the dye follows second-order kinetics.
