TITANIUM OXIDE, PHOTOCATALYST AND PHOTOCATALYST COATING COMPOSITION USING THE SAME

摘要

PURPOSE: Provided are titanium oxide that shows sufficiently high photocatalytic activities by irradiation of visible light, a photocatalyst using the titanium oxide as a catalyst component, and a photocatalyst coating composition using the titanium oxide. CONSTITUTION: The titanium oxide has a selected ion chromatogram in which an evolution gas having a ratio of mass number to electric charge quantity of 28 exhibits at least one peak at about 600 deg.C or higher. The selected ion chromatogram is measured by thermogravimetry-mass-spectroscopy. The peak of the evolution gas having a ratio of mass number to electric charge quantity of 28 is exhibited at about 950 deg.C or lower. The selected ion chromatogram is measured under a condition of applying a Channeltron Electron Multiplier voltage of 1000V.
