| Popis: | 106 Solar photocatalysis using partial shell-core Ag/P3HT@TiO2 as catalysts for the degradation of carbofuran pesticide wastewater was investigated in this study. The nano-photocatalyst of Ag/P3HT@TiO2 composite was prepared by a novel partial shell-core method and photoreduction method. The physical and chemical properties of Ag/P3HT@TiO2 nano-particles were characterized by Flame Atomic Absorption Spectrometry (AAS), the results showed that a 95% of the noble metal (Ag0) could be deposited on the surface of TiO2 in 5 minutes. The results of Scanning Electron Microscope (SEM) and X-ray Energy Dispersive Spectrometer (EDS) showed the prepared Ag/P3HT@TiO2 was indeed a partial shell-core type, and TiO2 was not completely covered by the addition of Ag and P3HT. The spectrum of UV/VIS Diffuse Reflectance Spectroscopy (UV/VIS DRS) showed that Ag/P3HT@TiO2 composites were much more responsive to visible light than TiO2. Accordingly, the drawback that TiO2 can only absorb part of sunlight (basically, λ |
