Title:
新規光触媒及びそれを用いた有害有機物質の無害化処理方法
Document Type and Number:
Japanese Patent JP4247780
Kind Code:
B2
Abstract:
To provide a photocatalyst not almost absorbing solar rays and capable of decomposing a harmful organic substance causing environmental pollution in a wide wavelength region with high use efficiency.
The photocatalyst comprises amorphous quartz glass subjected to hydrohalogenic acid treatment. A mixture of the harmful organic substance and oxygen is brought into contact with the photocatalyst while irradiated with radiation to optically decompose and detoxify the harmful organic substance.
