“…The activity and selectivity of the electrocatalytic reaction are essentially determined by the binding energy of the intermediate in multiple reaction steps. [126][127][128] The binding energies of different intermediates are proportional to each other through thermodynamic scaling. 129 For pure singlecenter catalysts, the chemical structure of the catalytic center is relatively simple, and it is difficult to optimize the binding energy of an intermediate without affecting other intermediates.…”

“…Atomic‐level structure – property tracking . Modern analytical methods combine precise atomic‐level architecture manipulation with ex situ, in situ, or operando characterization to study the local chemical states, doping‐intercalation processes, and property–structure relationship, etc [108–111] . These advanced operator‐controlled characterization techniques enable atomic‐level structure–property understanding in monitoring, visualization, and analysis towards various energy/chemical‐related transformations [112–115] .…”

Heterogeneous catalysts with targeted functionality can be designed with atomic precision, but it is challenging to retain the structure and performance upon the scaled‐up manufacturing. Particularly challenging is to ensure the “atomic economy”, where every catalytic site is most gainfully utilized. Given the emerging synergistic integration of human‐ and artificial intelligence (AI)‐driven augmented designs (AD), augmented analytics (AA), and augmented reality manufacturing (AM) platforms, this minireview focuses on single‐atom heterogeneous catalysts (SAHCs) and examines the current status, challenges, and future perspectives of translating atomic‐level structural precision and data‐driven discovery to next‐generation industrial manufacturing. We critically examine the atomistic insights into structure‐driven SAHCs functionality and discuss the opportunities and challenges on the way towards the synergistic human‐AI collaborative data‐driven platform capable of monitoring, analyzing, manufacturing, and retaining the atomic‐scale structure and functions. Enhanced by the atomic‐level AD, AA, and AM, evolving from the current high‐throughput capabilities and digital materials manufacturing acceleration, this synergistic human‐AI platform is promising to enable atom‐efficient and atomically precise heterogeneous catalyst production.

[112][113][114][115] For instance, except for metal atom re-dispersion or agglomeration that can sause the coexistence of clusters or nanoparticles in SAHCs system, the unsaturated local atomic configuration drives SAHCs themselves instability through dissociation and segregation proc- ess, thus leading structure reconstructions and deactivation.…”
