Abstract
Provided are a photocatalyst electrode for oxygen generation exhibiting a satisfactory onset potential, and a module including this photocatalyst electrode. The photocatalyst electrode for oxygen generation includes a current collector layer; a photocatalyst on the current collector layer; and a promoter supported on at least a portion of the photocatalyst, in which the promoter contains a first metal oxide having an oxygen generation overvoltage of 0.4 V or lower, and a second metal oxide having an oxygen generation overvoltage of higher than 0.4 V.
