Beyond d‐Band Catalysis: A Critical Review and Descriptor Framework for Rare‐Earth Engineering in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Rare‐earth catalysts regulate lithium–sulfur battery chemistry through f‐orbital–mediated interactions, enabling simultaneous polysulfide adsorption and catalytic conversion on conductive carbon hosts. This synergistic control suppresses the shuttle effect, accelerates redox kinetics, and guides stable Li2S nucleation, providing a mechanistic framework

The effects of popcorn-like CeO2 decorated Cr2AlC hybrid on the tribological properties of CF/PTFE fabric composites

Friction
In this study, cerium oxide (CeO2) nanoflowers were uniformly grown on the surface of chromium aluminum carbide (Cr2AlC) particles via a simple and efficient coprecipitation approach, which resulted in the preparation of the hybrids referred to as Cr2AlC@

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

The effect of Rh-CeO2 interface on carbon depostition on Rh-CeO2/Al2O3 during Ch4/CO3 reforming

, 2006
Three types of carbon species were found on Rh supported on Al2O3, Rh crystals and support over Rh/Al2O3, respectively. On CeO2-promoted Rh/Al2O3, the presence of Rh-CeO2 interface increased both the amount and reactivity of the carbon formed on Rh ...

Reconstruction of Nickel Chalcogenide Induced Ruthenium Nanoparticles Embedding for Oxygen Evolution: Mechanism Switching Enables Enhanced Catalytic Activity

Advanced Science, EarlyView.
Ru nanoparticles supported nickel chalcogens (Ru/NiX, X = S, Se), which enable fast electrooxidation to form an adaptively Ru embedding structure, featured by the compressed Ru─O─Ni bridge bonds at the Ru/NiOOH interface. On the one hand, Ru nanoparticles have a high affinity for capturing the OH−, consequently increasing the *O radical coverage.
