Title:
PHOTOCATALYST AND METHOD OF PHOTOCATALYTIC REACTION
Document Type and Number:
Japanese Patent JP2006224036
Kind Code:
A
Abstract:

To provide a novel photocatalyst and a method of a photocatalytic reaction which can efficiently perform a photocatalytic reaction such as a nitrogen containing organic compound.

The photocatalyst is provided with a core 12 consisting of a semiconductor nano particle and a shell 14 covering the core 12 through a void 13, and comprises a core/shell structural body having the void controlled inside of the shell 14. The photocatalytic reaction (excluding a dehydrating reaction of methanol as a substrate) is performed by an electron and/or a positive hole generated by the photoirradiation of the semiconductor nano particle. The core comprising at least two different nano particle composite bodies may be used which are bonded with the semiconductor nano particle and the catalyst nano particle. According to the photocatalytic reaction using the photocatalyst, azoxybenzene is selectively synthesized from nitrobenzene which is available as an intermediate for medical use.
