Single atoms as a catalyst: Surprising effects ensue – EurekAlert
Catalysts are getting smaller – ”single-atom” catalysts are the logical end point of this downsizing. However, individual atoms can no longer be described using…
Metals such as gold or platinum are often used as catalysts. In the catalytic converters of vehicles, for example, platinum nanoparticles convert poisonous carbon monoxide into non-toxic CO2. Because platinum and other catalytically active metals are expensive and rare, the nanoparticles involved have been made smaller and smaller over time.
