    Renewable Energy Breakthrough: Solar-powered Reaction 100 Times Faster

    September 2, 2016, Categories  Technology/Electronics, Chemistry/Nanotechnology

    A simulation shows one possible way that a highly active iridium oxide layer could form on the surface of a strontium iridium oxide catalyst. Experiments by SLAC and Stanford researchers showed that strontium atoms (green spheres) left the top layer through a corrosion process during the catalyst’s first two hours of operation. The top layer then rearranged itself and became much better at accelerating chemical reactions. Follow-up X-ray studies at SLAC will examine these surface changes in more detail. (C.F.
