Abstract
The TiO₂ photocatalysts with special morphology were synthesized in this paper. The authors used malus micro malus leaves and in docalamus leaves as template, and tetrabutyl titanate (TBT)as Ti source. The special shaped TiO₂ photocatalysts have high photocatalytic activity because of its unique morphology and s tructure. The structure and morphology of TiO₂ were characlerized by XRD and SEM, respectively. The photocatalytic activities were examined by the photodegradation of methylene blue (MB) under ultraviolet light (λ=365nm) iradiation. The results indicated that the TiO2 photocatalyst,using indocalamus leaves as templates, exhibited better adsorption and photocatalytic performance in degrading MB than using malus micro malus leaves, when the amount of nitric acid was 20 mL and following heat treatment at 600 ℃.
