Title: STRUCTURE AND PRODUCTION METHOD THEREFOR
Abstract:
Provided are: a structure with high photocatalytic activity; and a production method therefor. The structure of an embodiment is characterized in that: the structure is provided with a first metal compound with a first crystal structure and a second metal compound layer which is located on the surface of the first metal compound and has a second structure that differs from the first crystal structure; and, in time-resolved spectroscopy measured 5 µs after laser pulse irradiation, the maximum value of super-absorption intensity for the first metal compound, which has the second metal compound layer on the surface thereof, in the 1000 cm-1 to 20000 cm-1 wavenumber range is in the 1000 cm-1 to 8000 cm-1 wavenumber range and the ratio of said maximum super-absorption intensity with respect to the super-absorption intensity at wavenumber 15000 cm-1 is at least 10 fold.
