title = "Synthesis with microwave-assisted sol-gel method and photocatalytic activity of quantum-sized TiO 2 under solar and ultraviolet irradiation",
abstract = "Quantum-sized TiO 2 had been prepared by using Ti(n-OC 4H 9) 4 as the raw material via a microwave-assisted sol-gel method. The influence of different processing temperature and time on the size of TiO 2 was researched. The TiO 2 was characterized by transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD). The prepared TiO 2 presents anatase phase structure by TEM and XRD. The photocatalytic activity of TiO 2 was evaluated by the degradation rate of methyl orange in aqueous solution. The particle size of TiO 2 was about 9.10 nm when the processing temperature was 160°C and the processing time was 90 min (160°C-90min), and the photocatalytic performance was the best under this size. When the initial concentration of methyl orange was 10 mg/L and the amount of quantum-sized TiO 2 was 0.6 g/L, the degradation rate of methyl orange under ultraviolet and solar irradiation at room temperature in 60 min were 40% and 86%, respectively.",
