Document Type and Number:
Japanese Patent JP5321847
Kind Code:
B2
Abstract:
According to one embodiment, there is provided an active material including a titanium oxide compound having a monoclinic titanium dioxide crystal structure and satisfying the equation (I). S1/(S2+S3)@1.9(I). In the above equation, S1 is the peak area of a peak existing in a wavelength range from 1430 cm-1 to 1460 cm-1, S2 is the peak area of a peak existing in a wavelength range from 1470 cm-1 to 1500 cm-1, and S3 is the peak area of a peak existing in a wavelength range from 1520 cm-1 to 1560 cm-1, in the infrared diffusion reflective spectrum of the active material after pyridine is absorbed and then released.
