AB  - High specific activity and cost effectiveness of single-atom catalysts hold 
      practical value for water gas shift (WGS) reaction toward hydrogen energy. We 
      reported the preparation and characterization of Ir single atoms supported on 
      FeO(x) (Ir1/FeO(x)) catalysts, the activity of which is 1 order of magnitude 
      higher than its cluster or nanoparticle counterparts and is even higher than 
      those of the most active Au- or Pt-based catalysts. Extensive studies reveal that 
      the single atoms accounted for  approximately 70% of the total activity of catalysts containing 
      single atoms, subnano clusters, and nanoparticles, thus serving as the most 
      important active sites. The Ir single atoms seem to greatly enhance the 
      reducibility of the FeO(x) support and generation of oxygen vacancies, leading to 
      the excellent performance of the Ir1/FeO(x) single-atom catalyst. The results 
      have broad implications on designing supported metal catalysts with better 
      performance and lower cost.
