| Abstract: | A new hollow sphere photocatalyst has been fabricated by combining Fe3O4 with nanoparticulate CdS. Their microstructures and photocatalytic behavior were examined by X-ray powder diffraction, transmission electron microscope, scanning electron microscope and ultraviolet and visible spectroscopy. These hollow nanostructures displayed superparamagnetism at room temperature. It showed higher activity on hollow sphere than solid particle as the catalysis result. |
