Support‐Controlled Reaction Pathways via Dynamic Sulfur‐Mediated Interfaces for Selective Urea Electrolysis

Advanced Functional Materials, EarlyView.
Sulfur‐doped graphitized carbon nanofibers act as adaptive catalyst–support platforms, enabling dynamic sulfur‐mediated reconstruction and strong metal–support interactions. This unique behavior enhances catalyst stability and controls reaction pathways, achieving highly selective urea oxidation (∼92% N2) coupled with efficient hydrogen evolution ...

Controlling Proton Migration in Oxide Heterostructures by Interfacial Chemical Potential Mismatch

Advanced Functional Materials, EarlyView.
Interfacial reconstruction of the proton chemical potential enables control of proton migration in oxide heterostructures. In TiO2/VO2 heterostructures, we found that increasing the TiO2 capping layer thickness by only several nanometers modulates the thermal stability of protons inserted into VO2.
