Title:
PHOTOCATALYST GRANULAR MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/121350
Kind Code:
A1
Abstract:
Disclosed are a photocatalytic reforming method, a photocatalyst granular material comprising photocatalyst crystals reformed thereby, and a preparation method therefor, the photocatalytic reforming method comprising the steps of: in order to separate a monatomic layer of a photocatalyst, hydrothermally synthesizing the photocatalyst by reacting the photocatalyst with an alkaline solution at a temperature of at least 100°C; and processing the hydrothermally synthesized photocatalyst so that crystals of the photocatalyst have tubular shapes.
