水素発生用電極及び水素発生用電極の製造方法
Document Type and Number:
Japanese Patent JP7320775
Kind Code:
B2
Abstract:
To provide an electrode for hydrogen generation that indicates photoelectrochemical properties to be a high current density and a noble onset potential, and a manufacturing method of an electrode for hydrogen generation.SOLUTION: An electrode for hydrogen generation that generates hydrogen from water with light includes a p-type semiconductor layer and an n-type semiconductor layer on a collection layer in this order. A co-catalyst is supported on the n-type semiconductor layer, and the p-type semiconductor layer contains Cu, S, at least one of Ga or In, and alkali metal as essential ingredients. The electrode for hydrogen generation includes the p-type semiconductor containing at least one of Zn or Se as necessary.SELECTED DRAWING: None
