In the article "Double-Walled Tubular Heusler-Type Platinum-Ruthenium Phosphide as All-pH Hydrogen Evolution Reaction Catalyst Outperforming Platinum and Ruthenium," Sung Jong Yoo, Sang Uck Lee, Kwangyeol Lee, and their colleagues discuss the development of double-walled PtRuP2 nanotubes as efficient and durable cathode catalysts in anion-exchange membrane water electrolyzers (AEMWEs). These nanotubes address the challenging kinetics of the non-acidic hydrogen evolution reaction, promoting the commercialization of AEMWEs. The researchers utilized ion-exchange techniques to create these nanotubes, which maximize synergistic interactions through atomically localized metal centers.
