Abstract:

Highly ordered TiO2／ZnO nanocomposites with core-shell structure were successfully fabricated by a two-step method(anodic oxidation and hydrothermal method). The nanocomposites were analyzed by means of a scanning electron microscope (SEM), double beam UV-vis spectrophotometer and transmission electron microscope (TEM). The photocatalytic activity of the prepared material was tested by taking methyl orange as a pollutant on the model and natural light as the light source. The results showed that, TiO2／ZnO composite photocatalyst could improve the utilization of sunlight, and  could show the best  catalytic activity under the condition of pH=3 solution and degraded under the sun for 5 hours,  which reached to 90%.

Key words: two-step method, photoactivity, TiO2／ZnO, methyl orange
