NANOSHEET, NANOHYBRID USING THE SAME, AND PREPARING METHOD OF THE NANOHYBRID

摘要

The present invention relates to a nanohybrid, a photocatalyst comprising the same, and a method for manufacturing the nanohybrid, wherein the nanosheet according to the present invention is a conductive ternary metal oxide nanosheet in which surface bonding properties are controlled by controlling the ratio of constituent elements, By combining this with quantum dots through a hybridization reaction, a nanohybrid with improved photostability and photoreactivity of quantum dots can be prepared. Accordingly, the nanohybrid of the present invention has significantly improved kinetic interfacial charge transport ability, visible light harvesting ability, electron mobility, and ability to inhibit photo-excited electron-hole recombination compared to conventional visible photocatalyst materials. The photocatalyst including the nanohybrid according to the present invention has excellent photocatalytic catalytic properties compared to conventional catalyst materials, and can be particularly useful as a catalyst for hydrogen evolution or ammonia fixing reaction. In addition, the method for manufacturing a nanohybrid according to the present invention enables such a nanohybrid to be manufactured through a simple process.
