Rationalization of Interactions in Precious Metal/Ceria Catalysts Using the d‐Band Center Model

open access: yesAngewandte Chemie - International Edition, 2013
A correlation between ceria reducibility and the precious-metal d-band center is reported for ceria-supported precious-metal catalysts. The results could provide the missing link to fully explain the occurrence of strong metal-support interaction (SMSI) and hydrogen spillover in catalysts that consist of dispersed metals in contact with reducible metal

Tuned d-band states over lanthanum doped nickel oxide for efficient oxygen evolution reaction

open access: yesNano Materials Science, 2023
The d-band state of materials is an important descriptor for activity of oxygen evolution reaction (OER). For NiO materials, there is rarely concern about tuning their d-band states to tailor the OER behaviors.
