Photocatalyst granular material and preparation method therefor

Abstract

Described 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.
