Deepening of knowledge on nanocrystalline photoactive materials with selfcleaning abilities and antibacterial effects.

The Cost Action 540 »Photocatalytic technologies and novel nanosurfaces materials - critical issues (PHONASUM)« in the Domain: Materials, Physical and Nanosciences, is a network of researchers and practitioners working in the field of photocatalysis from all around Europe. The main objective of the Action is to increase via a concerted European effort the fundamental knowledge of nanocrystalline photoactive materials and development of new products, which utilize self sterilizing and self cleaning photoactive materials in specific industrially relevant application fields such as self-cleaning and anti-microbial surfaces, water treatment, air purification and general hygienic applications. The realization of these tasks will be accomplished through the development of novel highly active photocatalytic nanomaterials and coating systems with increased sensitivity in the visible region of the solar spectrum, with high environmental stability and adaptability on the various substrate systems. The Action will also concentrate on the development of EU standards for the characterization of photocatalytic materials. The Action commenced in January 2006 and will continue for four years.
