Abstract
Oxidation chemistry is centered around understanding the electron flow that involves reactants, products, and reaction-derived adsorbate species. In chemical sensing, this electron flow results in electrical conductivity modulations in a thin film of semiconductor (oxide) nanoparticles. Therein, understanding which surface-adsorbed species are electronically coupled to the material is crucial. Here, we develop a methodology that separates ionized from dipolar surface populations, to elucidate the unusual promoter effect of humidity on metastable, nanocrystalline CoCu 2 O 3 . Our results outline strategies to turn humidity from detrimental to a functional advantage in gas sensor performance.
