First nanoscale look at a reaction that limits efficiency of generating clean hydrogen fuel


SLAC
With a new suite of tools, scientists discovered exactly how tiny plate-like catalyst particles carry out a key step in that conversion – the evolution of oxygen in an electrocatalytic cell – in unprecedented detail.
Transitioning from fossil fuels to a clean hydrogen economy will require cheaper and more efficient ways to use renewable sources of electricity to break water into hydrogen and oxygen.
But a key step in that process, known as the oxygen evolution reaction or OER, has proven to be a bottleneck. Today it’s only about 75% efficient, and the precious metal catalysts used to accelerate the reaction, like platinum and iridium, are rare and expensive. ....

Giorgio Metta is scientific director of the Italian Institute of Technology (IIT), the Italian counterpart of the Massachusetts Institute of Technology (MIT). The institute has a multidisciplinary approach and is particularly strong in technology transfer. Metta (51), an electrical engineer who graduated from the University of Genoa (from which he also received his PhD), is considered to be the father of the iCub. This is a humanoid robot designed by several different European universities with the aim of conducting research on human cognition and artificial intelligence. ....
