Cheaper, less toxic and recyclable light absorbers for hydrogen production

Achieving artificial photosynthesis in solution remains limited by the use of costly and toxic metal-based compounds to harvest light. Researchers now propose an efficient alternative using semiconductor nanocrystals (also called quantum dots) based on cheaper and less toxic elements, such as copper, indium and sulfur.
