Abstract
Official abstract text for this publication.
Provided are a photocatalyst having higher activity for hydrogen production through water splitting and a photoelectrode comprising the photocatalyst. The photocatalyst for water splitting of the present invention comprises a Ga selenide, an Ag—Ga selenide, or both thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of splitting water, comprising: contacting water with a photocatalyst, wherein said photocatalyst comprises both Ga 2 Se 3 and an Ag—Ga selenide, and wherein an atom ratio between Ag and Ga in the photocatalyst is between 0.11 and 0.75, inclusive. 2. The method as claimed in claim 1 , wherein said Ag—Ga selenide is selected from the group consisting of AgGaSe 2 , AgGa 5 Se 8 and a combination thereof. 3. The method as claimed in claim 2 , wherein said Ag—Ga selenide is AgGaSe 2 . 4. The method as claimed in claim 1 , wherein said Ag—Ga selenide is AgGa 5 Se 8 . 5. The method as claimed in claim 1 , wherein said photocatalyst further comprises at least one of Rh and Pt supported thereon. 6. A method of splitting water, comprising: contacting water with a photoelectrode comprising a substrate, an electrically conductive layer formed on said substrate, and a photocatalyst layer formed on said electrically conductive layer and consisting of a photocatalyst, wherein said photocatalyst comprises both Ga 2 Se 3 and an Ag—Ga selenide, and wherein an atom ratio between Ag and Ga in the photocatalyst is between 0.11 and 0.75, inclusive.
