Evidence Alignment and Transfer Boundaries in Electrocatalytic Active-Site Design

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. Two target papers are triangulated against 12 locally validated publications. The comparison follows coordination structure, adsorption energetics, selectivity, operando evidence, durability and deliberately separates mechanistic interpretation from performance ranking, because the latter can conceal incompatible experimental or operational conditions. 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. The article concludes with a research agenda built around transparent comparators, targeted stress tests, and evidence records that can be reused without overstating causal or practical reach.
