<P>PROBLEM TO BE SOLVED: To provide a new visible light-responsive composition which exhibits high photocurrent responsiveness to visible light irradiation and provides a photocatalyst and an optical sensor. <P>SOLUTION: The visible light-responsive composition includes Fe, Ti, Zn and oxygen, wherein when the sum total of Fe, Ti and Zn is considered to be 100%, an element content ratio (molar ratio) is within the range of Fe:89-92%, Ti:1-10% and Zn:0.1-10%. A photoelectrode, an optical sensor and a photocatalyst each comprising the visible light-responsive composition is provided. A water electrolysis method using the optical sensor or photocatalyst is also provided. <P>COPYRIGHT: (C)2011,JPO&INPIT |
