Oxidized Ti Single Atoms and Co₃O₄ with Abundant Oxygen Vacancies Collaborating with Adjacent Pd Sites for an Efficient and Stable Oxygen Reduction Reaction

open access: yesAdvanced Science, EarlyView.
ORR pathways on the surface of CP@Ti‐1 catalyst, where oxygen vacancies in Co‐oxide and oxidized Ti single atoms promote the O2 splitting while adjacent Pd sites trigger the subsequent hydration step. Abstract The current study addresses these key issues by providing the ensemble sites and creating oxygen vacancies in the oxidized Ti‐single atoms. Here

Sulfur Bridge Geometry Boosts Selective FeIV═O Generation for Efficient Fenton‐Like Reactions

open access: yesAdvanced Science, EarlyView.
The sulfur bridge regulated the geometry and electronic effects of Fe diatomic pairs for selective and efficient generation of FeIV═O, opening an avenue to tune the microenvironment of active atomically dispersed sites and increase their loading amounts. Abstract High‐valent iron–oxo species (FeIV═O) is a fascinating enzymatic agent with excellent anti‐

The Function of Photocatalytic Performance and Carrier Separation Efficiency Tuned by Doping Content in Homogeneous Photocatalysts

open access: yesAdvanced Science, EarlyView.
A doping model of homogeneous photocatalysts of TiO2 is constructed to directly show the mapping relationship between carrier separation efficiency and photocatalytic performance. TRPL, KPFM, fs‐TAS measurements further quantify the carrier dynamics process. The photocatalytic performance of this series samples is dominated by the optimal conditions of

A Bifunctional Fibrous Scaffold Implanted with Amorphous Co2P as both Cathodic and Anodic Stabilizer for High‐Performance Li─S Batteries

open access: yesAdvanced Science, EarlyView.
An amorphous Co2P‐embedded porous carbon nanofiber membrane (A─Co2P/PCNF) via electrospinning/in situ phosphorization is developed to serve as the dual‐electrode stabilizer for Li─S batteries. The amorphization strategy enables more exposed undercoordinated Co sites with optimized d‐band centers, enhanced LiPSs adsorption/catalysis, and lithiophilicity‐
