Visible light sensitive photocatalyst, method of producing visible light sensitive photocatalyst, and electrochemical water decomposition cell and organic material decomposition system each including visible light sensitive photocatalyst

Abstract

A visible light sensitive photocatalyst including: a composite including a first metal oxide, a second metal oxide, and a heterojunction therebetween, wherein the first and second metal oxides each include a Group 11 metal, wherein a first bond between metal atoms of the first metal oxide has a length that is smaller than a Van der Waals distance between the metals of the first bond, wherein a second bond between metal atoms of the second metal oxide has a length that is smaller than a Van der Waals distance between the metals of the second bond, and, wherein the composite has a band gap energy of about 1.0 eV to about 2.5 eV.

Dependencies are inferred from the claim text.
