RSC Corday Morgan Award Lecture - Solar-driven Reforming of Waste Polymers for the Synthesis of Sustainable Fuels and Chemicals

Main list: RSC Award Lectures


Erwin Reisner

The synthesis of solar fuels and chemicals through artificial photosynthesis allows the direct pairing of light absorption to drive chemical redox processes. This approach is a one-step and versatile alternative to the more indirect coupling of a photovoltaic cell with electrolysis and enables potentially the synthesis of a wide range of fuels and feedstock chemicals. A common drawback in most artificial photosynthetic systems and organic photocatalysis is their reliance on expensive materials and device architectures, which challenges the development of ultimately scalable devices. Another limitation in many approaches is their inefficiency and reliance on sacrificial redox reagents, which may be system damaging and often prevent truly energy-storing chemistry to proceed. This presentation will give an overview about our recent progress in developing semiconductor suspension systems to perform efficient full redox cycle solar catalysis with inexpensive components, and our approach for sustainable waste polymer (biomass and plastics) photoreforming and fine chemical synthesis.
