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 ...

Surface‐Exposed Pd Nanocluster Confined within a Ring‐Shaped Polyoxometalate for Selective Hydrogenation

open access: yesAdvanced Science, EarlyView.
A small Pd nanocluster is successfully prepared within a ring‐shaped polyoxometalate via a mild solid‐state reduction process. The resulting surface‐exposed Pd nanocluster functions as a robust heterogeneous reusable catalyst, enabling highly chemoselective hydrogenation of substrates containing multiple reducible functional groups via selective ...
