Nanobrook Omni测量应用案例-64

The Fe3O4 quantum dots anchored SnO2 nanofibers (Fe3O4 QDs/SnO2 NFs) and CdTe quantum dots anchored SnO2 nanospheres have been prepared via hydrothermal method. The characteristic structure of Fe3O4 QDs/SnO2 NFs and CdTe QDs/SnO2 NSs was analyzed using several techniques such as X-ray diffraction, transmission and scanning electron microscopy, UV–Vis and photoluminescence spectroscopy, and N2 adsorption–desorption instruments. The average diameters of Fe3O4QDs/SnO2 NFs and CdTe QDs/SnO2 NSs were 7.25 and 3.75 nm, respectively. BET surface area of Fe3O4QDs/SnO2 NFs and CdTe QDs/SnO2 NSs has been found 53.064 and 148.59 m2/g, respectively. The Fe3O4 QDs/SnO2 NFs and CdTe QDs/SnO2 NSs sample were used for removal and photo-catalytic of carcinogenic compounds such as ethyl methanesulfonate (EMS) and N-nitrosonornicotine (NNN).
