Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

open access: yesAdvanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

The Role of Zn–Hf Site Proximity and Oxygen Vacancies for Methanol Formation Over ZnHfOx Catalysts Under CO2 Hydrogenation Conditions

open access: yesAngewandte Chemie, EarlyView.
ZnHfOx catalysts enable highly selective hydrogenation of CO2 to methanol over a wide range of Zn contents, as the Zn‐VO‐Hf active motif (VO = oxygen vacancy) exists not only in solid solution‐type ZnHfOx for low Zn contents (≤ 35 mol%), but also as HfOx cluster/single atom decorated ZnO surfaces for Zn contents > 95 mol%.
