    摘要: A modified natural graphite material which provides a negative plate having improved adhesion between a negative electrode mixture and a current collector has a circularity of at least 0.92 and at most 1.0 and an incident angle dependence S60/0 of the peak intensity ratio of at least 0.5 and at most 0.7 as determined by measurement of C K-edge X-ray absorption spectra using synchrotron radiation as an excitation source. It preferably satisfies at least one of the following conditions: an absolute specific gravity of at least 2.25 (g/cm3), a tap density of at least 1.0 g/cm3 and at most 1.4 g/cm3, and linseed oil absorption of at least 20 cm3/100 g and at most 50 cm3/100 g. A carbonaceous material may adhere to at least a portion of the surface of the graphite particles.

    摘要: A highly active titanium oxide photocatalyst of the type responsive to visible light is prepared by subjecting a titanium (hydr)oxide raw material obtained by neutralizing an acidic titanium compound in ammonia or an amine under conditions such that the final pH is 7 or below to heat treatment in an atmosphere containing a hydrolyzable compound followed by contact with water and additional heat treatment at a temperature of at least 350° C. The resulting titanium oxide photocatalyst comprises titanium oxide with a specific surface area of at most 120 m2/g and with the amount of surface hydroxyl groups being at least 600 μeq/g. Preferably the density of surface hydroxyl groups is at least 8 μeq/m2, and the ratio of the amount of terminal type hydroxyl groups (T) to the amount of bridge type hydroxyl groups (B) in the surface hydroxyl groups satisfies T/B≧0.20. This titanium oxide photocatalyst has an ESR spectrum having two types of triplet signal for which the g values of the main spectra are 1.993-2.003 and 2.003-2.011, respectively, and it is also identified by having ratios of the strengths of these signals before irradiation with visible light, under irradiation, and immediately after the stop of irradiation which are different from conventional products.

    摘要: A titanium oxide-based photocatalyst which can exhibit excellent photocatalytic properties in response to visible light while maintaining its inherent activity in response to ultraviolet light and which is suitable for mass production contains bismuth as a first additional metal component and at least one metal element selected from silicon, zirconium, aluminum, and hafnium as a second additional metal component in titanium oxide. The Bi/Ti atomic ratio is preferably at least 0.0001 and at most 1.0, the atomic ratio of the second additional metal to Ti is preferably at least 0.0001 and at most 0.8, and a portion of bismuth is preferably present in the form of lower valence (Bi2+ or Bi0). The presence of lower valence bismuth can be ascertained by XPS analysis.
