Title:

A visible light response constituent, the photoelectrical pole and photocatalyst using this, a photosensor

Document Type and Number:

Japanese Patent JP6229469

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a novel visible light responsive composition exhibiting high photocurrent response to visible light irradiation, and capable of being employed for forming a photoelectrode, a photocatalyst and an optical sensor.SOLUTION: The visible light responsive composition comprises Pb, Cr, Fe, and oxygen, wherein their element content ratios (molar ratios) are in the ranges of Pb: 40-90%, Cr: 10-40%, and Fe: 0-40% when the total of Pb, Cr, and Fe is 100%. Provided also are a photoelectrode, an optical sensor or a photocatalyst formed by the visible light responsive composition, and a water decomposition method using the optical sensor or photocatalyst.
