Counting charges per catalyst nanoparticle by electron holography (IMAGE)
Caption
This new study highlights the importance of directly counting electric charges in a catalyst nanoparticle. For example, in a platinum nanoparticle on a surface of titanium oxide, the visualization of potential distribution by the developed noise reduction process in electron holography revealed negative charging of the nanoparticle with just six extra electrons. This is the first time charges per catalyst nanoparticle were counted with an accuracy of one electron charge.
