In Situ Surface Reconstruction and Carbon Encapsulation for High‐Performance Pt‐Lean Catalysts beyond Conventional Core–Shell Designs

Small, EarlyView.
A one‐step in situ fabrication produces Pt‐segregated nanoparticles encapsulated in porous carbon shells. This design drastically reduces Pt content while maintaining high oxygen reduction reaction activity and long‐term durability. The catalyst meets DOE targets even at ultralow Pt loading, presenting a practical pathway toward cost‐effective, high ...

Nanostructuring Copper Tungstate Photoanodes: Performance Enhancement and Fundamental Limitations

Small Structures, EarlyView.
Nanostructuring of CuWO4 photoanodes yields a ~ tenfold photocurrent enhancement compared to dense films, reaching 0.6 mA cm−2 at 1.23 V versus reversible hydrogen electrode, among the best values reported for this material. Yet, performance remains far below the theoretical limit due to severe bulk recombination and poor electron transport ...
