Artful single-atom catalyst for sustainable chemical and pharmaceutical synthesis

a) Rational design of ASAC for cross-coupling reactions, where M1 represents the foreign single metal atom introduced onto the reducible carriers. (b) Using a single-atom of Pd1 anchored on the material CeO2 as a representative example, this panel illustrates the dynamic structural and valence state evolution of the Pd1 ASAC. These changes help it avoid the usual challenge in cross-coupling reactions, which is the energy barrier associated with oxidative addition. This is in contrast to traditional homogeneous catalyst systems, where the reaction rate is largely limited by this step.
