Abstract
Carbon spheres as template with hydrothermal method we prepared TiO2,ZnO, and TiO2/ ZnO composite hollow spheres of 1:2. The samples are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), EDS and UV-Vis. Photo degradation activity of composite hollow spheres is studied for two dyes Methylene Blue(MB), and RhodamineB(RhB)at different time intervals (0-270min) under UV Lamp(54 watts).The results are systematically analysed and reported at the end ,the degradation efficiency of TiO2/ ZnO (1;2) hollow spheres is about 90% within 270 min.
