Abstract
Research spanning electrocatalytic active-site design increasingly joins methods that were developed for different objects and decisions. Here, chalcogenide-anion regulation of Ni2Mo6Te8 stability and nitrate-to-ammonia selectivity is compared with cooperative atomically dispersed Fe-N4 and Sn-Nx coordination sites for oxygen reduction to determine which claims can travel across those boundaries and which remain context dependent. The analysis combines two focal publications with 12 previously verified sources and organizes the evidence around coordination structure, adsorption energetics, selectivity, operando evidence, and durability. Rather than pooling incompatible outcomes, it compares research questions, representations, controls, and validation envelopes. The synthesis shows that coordination structure cannot be interpreted independently of adsorption energetics, while selectivity determines whether an apparent improvement remains meaningful outside the original setting. The strongest claims are therefore those that expose sensitivity, failure conditions, and residual uncertainty. 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.
