Abstract
Research spanning electrocatalytic active-site design increasingly joins methods that were developed for different objects and decisions. Here, cooperative atomically dispersed Fe-N4 and Sn-Nx coordination sites for oxygen reduction is compared with chalcogenide-anion regulation of Ni2Mo6Te8 stability and nitrate-to-ammonia selectivity to determine which claims can travel across those boundaries and which remain context dependent. The review draws on two focal records and 12 established sources already present in the project evidence cache. Its comparative framework links coordination structure, adsorption energetics, and selectivity to downstream questions of operando evidence and durability. Comparison reveals recurring trade-offs among coordination structure, adsorption energetics, and selectivity. These trade-offs do not support a universal ranking; instead, they identify the operating envelope within which each method remains credible and the perturbations most likely to expose fragile conclusions. On this basis, the review proposes an auditable pathway from focal mechanism to application claim, with explicit checkpoints for calibration, external validity, and responsible interpretation.
