Sr{sub 2}TiO{sub 4}:Cr complexes are found to possess photochromism. After the photochromism, the catalytic performance of the complexes for H{sub 2} generation increases markedly. In fact, it was found that the performance increased more than 20 times compared to the original Sr{sub 2}TiO{sub 4}: 10 mol % Cr complex. These results suggest that it is worthwhile searching and optimizing visible-light-sensitive photocatalysts by investigating possible photochromism.
