HYBRID PHOTOCATALYSTS, THE METHOD OF THEIR SYNTHESIS AND USE

IP Title

Summary

The subject of the invention is a hybrid photocatalyst which is a layered aluminosilicate, possibly organically modified, containing compounds introduced into the aluminosilicate galleries bearing groups such as porphyrin, rose bengal, anthracene, pyrene, perylene, tetracene, rubrene, naphthalene, phthalocyanines, coumarins, and methylene blue, which are organic chromophores able to absorb visible and/or ultraviolet light and sensitize photochemical reactions. The invention includes also the met

Technology Application

Water contamination becomes a problem which may limit civilization progress.The development of a universal and inexpensive method of water purification is very difficult, because it may contain pollutants of different nature, e.g. heavy metals, organic compounds (pesticides, chlorinated aromatic compounds, antibiotics and surfactants) as well as bacteria. The water purification methods currently in use are based on osmosis, ion-exchange, adsorption, ultrafiltration, distillation and photooxi

Title: Polymer-aluminosilicate hybrid photocatalyst, method of its obtaining and its application
Usefulness: Polymer-aluminosilicate hybrid photocatalyst, method of its obtaining and its application
Summary: The hybrid photocatalysts is useful: in the photocatalytic degradation of water impurities; to remove phenol, phenol derivatives, chlorinated aromatic pollutants, pesticides, and polycyclic aromatic compounds, by their photocatalytic degradation; for the removal of organic pollutants; and for removal of cyanides by their photocatalytic oxidation to cyanates (all claimed).
Novelty: Hybrid photocatalyst (organically modified aluminosilicate), used e.g. in removal of phenol, comprises organic chromophores e.g. anthracene, which absorb visible or ultraviolet light and sensitize photochemical reactions
