▎ 摘　　要

NOVELTY - Producing hybrid photocatalytic nanoparticles comprises wrapping a graphene oxide to a surface of photocatalytic nanoparticles; and then performing the hydrothermal reaction along the graphene oxide wrapped photocatalytic nanoparticles. USE - The method is useful for producing hybrid photocatalytic nanoparticles (claimed) that are useful in an energy device and an electrode device. ADVANTAGE - The method is capable of easily producing the hybrid photocatalytic nanoparticles without activating the catalyst or performing the carbonizing process and with improved photocatalytic activity in the visible region and in an UV region.
