catalyst assembly schematic (IMAGE)
Caption
A schematic showing how single platinum atoms (Pt SA) on a cerium oxide surface self-assemble at elevated temperature (T) to become active nanocatalyst (NC) particles. At high temperature, the catalyst converts hydrogen (H2) and carbon dioxide (CO2) into water (H2O) and carbon monoxide (CO). Upon cooling, the nanocatalyst particles disassemble into single platinum atoms that can be reactivated and used again.
