Unveiling Alkali‐Induced Redox Modulation: In‐Situ Spectroscopic Insights from RWGS on Alkali‐Modified ZrO2‐Supported Cu Catalysts

open access: yesAdvanced Science, EarlyView.
Revisiting the prevailing views that alkali only enhances adsorption properties and stabilizes metal particles against sintering, this study highlights the key role of Na+ in modulating Cu redox properties. Na+ added via wet impregnation (WI) hinders Cu2+ reduction but promotes oxidation and leads to Cu site loss by sintering/coverage. In contrast, the

Pyrolysis‐Free Formed Cooperative Coupling Pt‐Co Dual‐Functional Sites for Saline Electrolysis with High Adaptability

open access: yesAdvanced Science, EarlyView.
Through a mild pyrolysis‐free route, cooperative coupling of single cobalt atoms (CoSA) and fully exposed platinum nanoclusters (PtNC) is assembled. As expected, the as‐prepared catalysts PtNC/CPF‐Co exhibit dual‐functional performance and high adaptability, demonstrating low overpotentials of 44 mV for HER and 340 mV for OER at 10 mA cm−2 in saline ...

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

open access: yesAdvanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

In Situ Utilization of Co‐Existing Metal Ions to Fabricate Single‐Atom Catalyst for Boosting Fenton‐Like Activity

open access: yesAdvanced Science, EarlyView.
A metal‐free TQBQ‐COF with pre‐designed anchoring sites captures coexisting Cu²⁺ from wastewater to form a single‐atom catalyst within 1 min. This in‐situ fabrication boosts visible‐light photo‐Fenton activity, enabling efficient removal of organics pollutants via 1O2 and holes.

Chronic PET‐Microplastic Exposure: Disruption of Gut–Liver Homeostasis and Risk of Hepatic Steatosis

open access: yesAdvanced Science, EarlyView.
Chronic exposure to environmentally relevant PET microplastics disrupts gut–liver homeostasis, leading to hepatic steatosis, early fibrosis, and altered gut microbiota. These effects signal metabolic imbalance and gut–liver axis impairment, emphasizing chronic microplastic ingestion as an emerging environmental health risk linked to non‐communicable ...
