Visible light induced catalytic properties of CdSe-graphene nanocomposites and study of its bactericidal effect

A novel composite, CdSe-graphene, was synthesized using facile hydrothermal method. The structural characteristics studies of the synthesized composites were investigated by X-ray diffraction （XRD）, scanning electron microscope （SEM）, transmission electron microscope （TEM）, Brunauer, Emmett, Teller...

More Information
Summary:A novel composite, CdSe-graphene, was synthesized using facile hydrothermal method. The structural characteristics studies of the synthesized composites were investigated by X-ray diffraction （XRD）, scanning electron microscope （SEM）, transmission electron microscope （TEM）, Brunauer, Emmett, Teller specific surface area （BET） and X-ray photoelectron spectroscopy （XPS）. The photocatalytic activity was investigated by the degradation of methylene blue as standard dye. The degradation of M8 was calculated based on the decrease in concentration of the dye with respect to regular time intervals. The reusability tests were done to investigate the stability of the used catalysts. Additionally the antibacterial activity of CdSe-graphene was also investigated using bacterium Streptococcus aureus （S. aureus）.
