Profile of the alliance

Who are we and what do we do?

The Fraunhofer Photocatalysis Alliance is a group of ten Fraunhofer institutes working together on the development of novel, highly effective photocatalysts which can be applied to a wide range of substrates such as glass, ceramics, plastic and metal.

Our main goal is to produce self-cleaning layers which degrade organic compounds and which also have a biocidal effect.

Other goals of our development work are:

  • to activate the photocatalysts with visible light, enabling indoor applications
  • to increase the photon yield
  • longer service life and easy regeneration
  • to customize the photocatalytic effect

The Photocatalysis Alliance uses a wide range of technologies to develop the layer systems, including vacuum plasma methods, sol-gel technology and water-based coatings.

In order to get rapid and reliable information about the catalytic activity of the layers, the Fraunhofer Photocatalysis Alliance is developing test methods for measuring the chemical-physical and microbiological properties.

The environmental compatibility and health safety of the photocatalytic layers are also important topics. In this regard, the Fraunhofer Photocatalysis Alliance is developing methods and processes for examining the biological effects of large-area outdoor applications of photocatalytic layers. In addition, standardized ecotoxicological methods, which are used for surface water and groundwater protection, are modified to the specific needs of photocatalysis.
