MESOPOROUS LAYER-BY-LAYER NANOHYBRIDS, PREPARING METHOD OF THE SAME, AND PHOTOCATALYST CONTAINING THE SAME

摘要

PURPOSE: A mesoporous layered nanohybrid with high photocatalytic activity for O2 production, a manufacturing method thereof, and a photocatalyst including the same are provided to enhance chemical stability. CONSTITUTION: A mesoporous layered nanohybrid with high photocatalytic activity for O2 production is formed by self-assembly of a layered double hydroxide(LDH) nanosheet and a metal oxide nanosheet. The mesopores are formed between the self-assembled nanosheets. A manufacturing method of the mesoporous layered nanohybrid comprises the following steps: preparing a first nanosheet dispersed solution containing metal layered dihydroxide nanosheets; preparing a second nanosheet dispersed solution containing metal oxide nanosheets; and self-assembling the metal layered dihydroxide nanosheets and metal oxide nanosheets by mixing the first nanosheet dispersed solution and the second nanosheet dispersed solution. The optical catalyst comprises the mesoporous layered nanohybrid.
