Catalysis by Supported Single Metal Atoms

Liu, Jingyue·2017·ACS Catalysis

Abstract

The recent explosive growth in research on catalysis by supported single metal atoms proves the scientific interest in this new frontier of heterogeneous catalysis. A supported single-atom catalyst (SAC) contains only isolated individual atoms dispersed on, and/or coordinated with, the surface atoms of an appropriate support. SACs not only maximize the atom efficiency of expensive metals but also provide an alternative strategy to tune the activity and selectivity of a catalytic reaction. When single metal atoms are strongly anchored onto high-surface-area supports, SACs offer a great potential to significantly transform the field of heterogeneous catalysis, which has been critical to enabling many important technologies. In this Perspective, I discuss the most recent advances in preparing, characterizing, and catalytically testing SACs with a focus on correlating the structural perspective of the anchored single metal atoms to the observed catalytic performances. The grand challenge to successfully developing practical SACs is to find appropriate approaches to strongly anchor the single metal atoms and to keep them stable and functional during the desired catalytic reactions. I will highlight the recent advances to overcome this barrier to develop SACs for a variety of important catalytic transformations of molecules.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
