Catalysts consisting of isolated oxophilic metal atoms on supports are established industrial catalysts, and intense interest has turned to noble metal atoms on supports, including those on metal oxides imaged with atomic resolution by aberration-corrected scanning transmission electron microscopy and those on single metal crystals imaged by scanning tunneling microscopy. Images and spectroscopic data bolstered by theory are determining precise structures of surface catalytic sites (including metal atoms and supports); insights into bonding and reactivity at these sites; and new, potentially valuable, catalytic properties, such as (a) high activities and stabilities of cationic metals on oxides for CO oxidation and the water gas shift and (b) high activities and selectivities of zero-valent metals in alloy structures for hydrogenations and C–H bond activation. The imaging capabilities especially have triggered the surge in research on these catalysts, which offer unprecedented opportunities for fundamental understanding, discovery, and even design of new catalysts. The presentation will be a summary of trends in research in this field.<br/>
