Oxygen‐Driven Reconstruction Activates Quasi‐Single Pd Sites in Hollow PdAg Nanotubes for Zinc–Air and Fuel Cells

open access: yesAdvanced Science, EarlyView.
A galvanic replacement strategy is employed to fabricate hollow PdAg alloy nanotubes, where interfacial oxygen triggers surface reconstruction and stabilizes quasi‐single Pd active sites. This atomic‐level engineering optimizes electronic configurations and enriches exposed catalytic centers, significantly boosting oxygen reduction reaction activity ...

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 ...

Strategically Constructing Alkali‐Metal Interfacial Bridges to Boost Photocatalytic CO2 Methanation on Supported Ni─Ru Bimetallic Catalysts

open access: yesAdvanced Science, EarlyView.
Strategically anchoring Na at the Ni─Ru/ZrO2 interface creates a robust Ni0─Niδ+─Na─O─Ru electronic bridge, significantly enhancing electron transfer and inter‐metal synergy. This interface accelerates photocatalytic CO2 methanation via stabilized *COOH intermediates and efficient H2 activation, boosting CH4 yield.

Axial and Asymmetric Coordination Coupling Adjust the Electronic Structure of Single‐Atom Zinc Sites for Efficient Electroreduction of Carbon Dioxide

open access: yesAdvanced Science, EarlyView.
Zn‐SACs are successfully synthesized with axial Cl and asymmetric S coordination (ZnN3S1Cl/C). The asymmetric coordination of S and the axial coordination of Cl can lead to electron redistribution near the single Zn site, increasing the overlap between the Zn (3d) and *COOH (2p) orbitals.
