Facile Synthesis of Nanoporous Pt-Ru Alloy Spheres with Various Compositions toward Highly Active Electrocatalysts

Into new spheres: We report a facile, one‐step, and low‐cost method for the synthesis of nanoporous Pt–Ru spheres with a high surface area, in which a commercially available block copolymer is used. The obtained unique dendritic nanoarchitecture, with an open nanoporous structure, is favorable for p...

Beschreibung
Zusammenfassung:	Into new spheres: We report a facile, one‐step, and low‐cost method for the synthesis of nanoporous Pt–Ru spheres with a high surface area, in which a commercially available block copolymer is used. The obtained unique dendritic nanoarchitecture, with an open nanoporous structure, is favorable for providing an unblocked transportation of guest species such as methanol molecules.
