OBJECTIVES
The main objective of this Action is to via a
concerted European effort increase the
fundamental knowledge of nanocrystalline
photoactive materials and development of new
products, which utilize self sterilizing and self
cleaning photoactive materials in commercial
applications. The Action will also concentrate on
the development of EU standards for the
characterization of photocatalytic materials.

SPECIFIC GOALS

• Development of novel highly active and resistant
  nanoparticulate photocatalytic materials
  sensitive also to the visible light
• Development of technically applicable self
  aligning photoactive coating systems adaptable to
  the most common substrates (polymers, glass,
  ceramics or metals)
• Characterization of physical and chemical
  properties of photocatalytic nanomaterials and
  coatings and design of standard photoactivity
  testing methods
• Utilization of new photocatalytically active
  nanomaterials and coating systems in specific
  industrially relevant application fields

Standardization
is required

• To increase the reliability
• To verify and compare the performance
• To develop more efficient materials
• To promote the use by public organizations
• To launch a new environmental industry
