In times of high risk of infection, effective protective measures are needed. Avoiding transmission routes via contaminated surfaces is an important part. It is known that photocatalytically active coatings reduce the microbial load. In order to increase the efficiency of this light-driven reaction, a novel active composition was developed and introduced into materials within the „Covid-DEKONT“ project. By combining copper-doped titanium dioxide with layered silicates, a synergistic effect was observed that brings pathogenic bacteria and viruses more effectively into contact with the catalysts and accelerates their inactivation.
