The diverse fields of application for photocatalytic products require application-specific measuring technology. Active photocatalytic film systems, surfaces and powders promise self-cleaning, cleaning assistance and antimicrobial characteristics. Determining the effectiveness and efficiency of breaking down adsorbed substances (bacteria, dirt, water...) serves as a measurement of the photocatalytic characteristics. However, a direct comparison between different materials is highly complex due to the complicated mechanisms of action at the boundary layer between the photocatalyst and reagent.
Fraunhofer IST offers numerous specific and standardised characterization methods for various application cases and surfaces. We make our many years of experience with a wide variety of analytical measuring methods fully available to our customers for product and technology development.
