Hybrid Photocatalysts, the Method of their Synthesis and Use
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 methods of synthesis and application of the photocatalysts for the photocatalytical degradation of water pollutants.
Hybrid photocatalysts based on layered nanoclays can become an attractive alternative method of water purification,particulary suitable for industrial plants using water in their technological process, e.g. in power, steel, chemical, pharmaceutial or food-processing plants. Moreover, they can be tailored for specific applications (pollutants).
The offered storm activity system is the subject of patent application (EPO, USA). Polish patent has been granted.
The application of the hybrid photocatalysts and the method of obtaining them are subject of a patent application. The research and development efforts concerning this technology are continued at the Faculty of Chemistry of the Jagiellonian University. Currently the Centre for Innovations, Technology Transfer
and University Development (CITTRU) is looking for companies and institutions interested in obtaining a license for the material and its applications described above.
