Summary:

A fundamental properties of nano-structured self-assembled selenium and sulfur materials and their role in catalysis of chemical reactions is a topic of outstanding interest in modern chemical science and process development. It is widely acknowledged that the size and shape of nanoparticles is of paramount importance in catalysis. On the other hand, the impact of nanoparticles organization on chemical reactivity remains largely unexplored. There is no clear-cut understanding how the morphology of nano-structured materials affects the chemical reaction’s rates and properties of resulting substances. Our studies revealed that utilization of intrinsic properties of nanoparticles may lead to a totally new approach that will make the catalysis much more efficient. Currently, development of new catalytic materials is mostly limited to trial and error method that may be very long, costly and inefficient. Our studies highlight a new approach that is fundamentally different by its nature and enable the tailored design of catalytic materials by avoiding a great number of unnecessary trials. The developed technology is evaluated for catalysis, biomedical research, environmental protection and materisl science. Application of Se and S monolayers resulted in a new generation of highly efficient catalysts that do not generate chemical wastes (Green and sustainable procedures).
