Preparation and Photocatalytic Properties of Fe(III)-Grafted TiO₂ Nano-Composite Powders

Abstract:

Fe(Ⅲ)-grafted TiO2 nano-composite powders were prepared by a physical mixture method of Fe（NO3）3·9H2O and TiO2, which was prepared by the pretreatment of blending Fe（NO3）3·9H2O and TiO2 (Fe molar fraction is 0.5%) in absolute ethanol and then calcined at 110 °C. The morphology and structure were characterized by SEM, XRD and UV-Vis spectroscopy, and the photocatalytic activities were evaluated by the decomposition of methyl orange. The experimental results show that the obtained Fe(Ⅲ)-grafted TiO2 nano-composite powder sample has a higher adsorption ability than that without Fe(Ⅲ)-grafting. The degradation of methyl orange due to physical adsorption reaches 53.2% for the as-prepared sample compared to that of TiO2. The sample also has a slightly higher photocatalytic activity. The photocatalytic apparent rate constant is about 1.09 times of that of TiO2. The reaction mechanism has also been discussed.
