dc.description.abstract | Nano-sized TiO2 terminals were linked with magnetic-cored dendrimers by a divergent method in this research. Significant improvement in photocatalytic activity was monitored in decolorization of methyl orange (MO) in comparison with bare nano TiO2 and Fe/Ti mixture at the same ratio. Enhanced photocatalytic activity of magnetic-cored dendrimers with nano-sized TiO2 (TD) can be attributed to restrained recombination of electron-hole pairs because of photoexcited electron capture in dendrimers. MO decolorization was facilitated by synergistic effect from surface adsorption and photocatalytic activity. Experimental results were fitted well with the Langmuir-Hinshelwood (L-H) model, which indicated that the photodecolorization after adsorption. The observed decolorization rate constant and the adsorption coefficient values were 0.0478 and 0.0812, respectively. Reuse of TD was also investigated for five successive runs. | - |
