Preparation and Photocatalytic Activity of Yellow Titania
Titania powder was prepared by a sol-gel method and heat-treatment (HT).The morphology and structure of the titania powder were characterized by X-ray diffraction (XRD),differential thermal analysis,transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS).The photocatalytic activity of powder was investigated using methyl orange as target compound.Colour changing of powder was due to colour centers form.Under visible light,yellow powder showed the better photocatalytic activity than P25 powder and its visible light response was expanded.Preparation of yellow powder lowered conventional calcinations temperature obviously.
