Researchers at the University of Zurich have developed a new type of nanoparticle for use in artificial photosynthesis. They are capable of producing clean hydrogen fuel from water and sunlight..
Scientists were able to achieve this effect by adding zinc sulfide to the surface of nanoparticles (3 nm) of indium. The new composite material is not only environmentally friendly but also very efficient in the hydrogen production process. In the course of research, it was found that sulfide ligands on the surface of quantum dots facilitate the most important stages associated with chemical reactions associated with light, namely the effective separation of charge carriers and their rapid transfer to the surface of nanoparticles.
In the future, indium-based water-soluble and biocompatible particles can be used to convert biomass into hydrogen. They can also be used as low toxicity biosensors or nonlinear optical materials. For now, however, the team will focus on developing catalysts for artificial photosynthesis as part of a priority university research program..
Recently, discoveries in the field of nanomaterials have occurred quite often. Scientists from Radbud University recently discovered a new mechanism for magnetic storage of information in one atom. at room temperature, based on a change in the energy levels of cobalt electrons.
