Catalyst enables reactions with the help of green light

For the first time, chemists at the University of Bonn and Lehigh University in Bethlehem (USA) have developed a titanium catalyst that makes light usable for selective chemical reactions. It provides a cost-effective and non-toxic alternative to the ruthenium and iridium catalysts used so far, which are based on very expensive and toxic metals. It can be used to produce highly selective chemical products that can provide the basis for antiviral drugs or luminescent dyes.
