JUNCTION PHOTOCATALYST

Title:

JUNCTION PHOTOCATALYST

Document Type and Number:

WIPO Patent Application WO/2023/167179

Kind Code:

A1

Abstract:

The present invention provides a junction photocatalyst having higher catalytic activity than conventional junction photocatalysts. The junction photocatalyst according to the present invention has a solid mediator between a hydrogen generating photocatalyst and an oxygen generating photocatalyst. The solid mediator and the hydrogen generating photocatalyst are bonded via an ionic polymer.
