Photocatalyst compound having nano hierarchical structure including noble metal and the fabrication method of it

摘要

The present invention relates to a photocatalytic composite in which a noble metal and a photocatalytic material have a nano-hierarchical structure, comprising: a photocatalytic material having crystals independent from each other; It is composed of a noble metal material, and the photocatalytic material and the noble metal material are characterized in that one of the photocatalytic materials and the noble metal material grows from the other surface to form an integrally combined form, so that the carrier recombination rate can be significantly suppressed than before, and in the visible light region. In order to provide a photocatalyst composite having a nano-hierarchical structure that has the effect of further enhancing photoreactivity by providing an auxiliary sink of electrons, as the photoresponse can be generated in a wide range of spectral wavelength bands. do.
