Sabatier‐Adjusted d‐Band Centers of Scalable Asymmetric Iron Sites toward Dynamic Nonradical Network for Fast Mineralization with Low‐Amount Oxidant

open access: yesAdvanced Science, EarlyView.
Asymmetric iron single‐atom catalysts with Sabatier‐adjusted d‐band centers overcome the inherent limitations of peroxymonosulfate (PMS) activation by establishing a synergistic nonradical pathway network, achieving exceptional pollutant mineralization (≈85%) at only one‐tenth conventional PMS dosage.

Defect‐Cascades‐Induced Photodegradation in InP/ZnSe/ZnS Quantum Dots

open access: yesAdvanced Science, EarlyView.
Surface sulfur vacancies in InP/ZnSe/ZnS quantum dots trigger vacancy cascades under blue light, propagating toward the ZnSe interface. In situ ESR (g = 2.004, 2.012) and DFT reveal a defect‐driven shift from type‐I to type‐II band alignment, reducing radiative recombination and EQE.

Selective and Long‐Term Stable Ammonia Electrolysis Using Pt–WOx Catalysts with Suppressed NOx Formation and Enhanced Activity

open access: yesAdvanced Science, EarlyView.
This study reports photodeposited Pt nanoparticles on WOx nanowires (Pt–WOx (P)) as a bifunctional catalyst for ammonia electrolysis. Strong metal–support interactions promote electron transfer to Pt, lowering the energy barrier of the rate‐determining step and suppressing NOx formation.
