Published: Feb. 14, 2023

Controlling the electronic structure of transition-metal single-atom heterogeneous catalysts (SACs) is crucial to unlocking their full potential. The ability do this with increasing precision offers a rational strategy optimize processes associated adsorption and activation reactive intermediates, charge transfer dynamics, light absorption. While several methods have been proposed alter characteristics SACs, such as oxidation state, band structure, orbital occupancy, spin, lack systematic approach application makes it difficult control effects. In Perspective, we examine how configuration SACs can be engineered for thermochemical, electrochemical, photochemical applications, exploring relationship activity, selectivity, stability. We discuss synthetic analytical challenges in controlling discriminating possible directions toward closing gap between computational experimental efforts. By bringing topic center, hope stimulate research understand, control, exploit effects ultimately spur technological developments.
