摘要

The process of preparing a nanostructured photocatalyst, nanostructured photocatalyst and its use The present invention describes the preparation of a family of permanent-use nanostructured photocatalysts that function in the mineralization of organic substances dissolved in water using natural sunlight. The photocatalyst of the present invention is used at the bottom of a shallow tank exposed to sunlight that will oxidize the dissolved organic substances and turn them into carbon dioxide, water and some water-soluble mineral salts. The material does not suffer from poisoning, nor does it lose its photodegradation properties over time. The photocatalyst of the present invention does not use electrical energy for irradiation, does not use visible or ultraviolet light bulbs and does not routinely use process-associated oxidizing substances which cause environmental problems in the disposal of oxidizing waste permanently and increase the process costs.
