Study on microwave hydrothermal synthesis of nanocrystal titanium dioxide photocatalyst and its photochemical performance
TiO2晶体的微波水热法制备及光催化性能研究

Using titanium sulfate and urea as raw materials, EDTA as control agent, TiO_2 photocatalyst with nanoscale structure was obtained through microwave hydrothermal synthesis. The corresponding formation factors were analyzed. The products were characterized by transmission electron microscopy (TEM) , X-ray diffraction (XRD). The results showed that the main crystalline phase of titanium dioxide was anatase and the particle was of nanoscale size and perfect dispersity after reacting for 150 rain in the microwave-hydrothermal vessels. Moreover, the further investigations indicated that these samples were of high photoeatalytic activity which was proved by the degradation experiments of acid-orange.
