Title:
PHOTOCATALYST ELECTRODE AND METHOD FOR MANUFACTURING PHOTOCATALYST ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2023/106225
Kind Code:
A1
Abstract:
The present invention provides a photocatalyst electrode and a method for manufacturing a photocatalyst electrode, the photocatalyst electrode exhibiting higher catalytic activity than conventional hematite catalysts and being capable of extracting hydrogen peroxide with greater efficiency than the conventional hematite catalysts. The present invention is obtained by layering a catalyst layer on a first principal surface of a substrate, and is configured such that the catalyst layer is formed by superposition and partial fixing of a plurality of hematite-based crystal particles; a shell layer being formed on the surface of a core body in the hematite-based crystal particles; the core body having iron oxide as the main component; the shell layer having a double oxide including a first metal and a second metal as the main component and an average thickness of 1-7 nm; and an oxide of the first metal and an oxide of the second metal each exhibiting photocatalytic activity.
