Abstract

Abstract: It is a challenge to make clear how isomerism in a heterogeneous catalyst induces distinct differences in catalytic properties, as attainment of the structural isomerism in a conventional catalyst is difficult. By successfully identifying the isomerism in the atomically precise Au nanoclusters, an exciting opportunity for unravelling catalysis of isomeric catalysts is opened up. Herein, we report that the isomerism in the Au28 (SR)20 nanoclusters with different surface atom arrangements can indeed render different catalytic behaviors in the selective hydrogenation of CO2 . We anticipate that our studies will serve as a starting point for fundamental investigations about how to control the catalytic activity and selectivity by the isomerism‐induced catalysis. Abstract : Control your catalyst ! It is unclear whether and how isomerism in a catalyst affects the catalytic performance. It is demonstrated that the structural isomerism in Au28 (SR)20 renders distinct catalytic behavior to the selective hydrogenation of CO2 . The isomerism‐induced catalysis provides guidance for how to control the catalytic activity and selectivity by the position arrangement of atoms in catalysts.
