In this critical review, we present the current technological advances in proton exchange membrane (PEM) fuel cell catalysis, with a focus on strategies for developing nanostructured Pt-alloys as electrocatalysts for the oxygen reduction reaction (ORR). The achievements are reviewed and the major challenges, including high cost, insufficient activity and low stability, are addressed and discussed. The nanostructured Pt-alloy catalysts can be grouped into different clusters: (i) Pt-alloy nanoparticles, (ii) Pt-alloy nanotextures such as Pt-skins/monolayers on top of base metals, and (iii) branched or anisotropic elongated Pt or Pt-alloy nanostructures.

Nuovo Cimento 1919, 18, 112-154). Perucca's chiroptical observations are apparently consistent with a resolution of the propeller-shaped dye molecules by NaClO(3) crystals.

Article Synopsis
- Eligio Perucca discovered the enantioselective adsorption of a racemic mixture to a chiral crystal (NaClO(3)) in 1919, marking a significant finding in enantioselective chemistry.
- Despite this important contribution, his work remained largely unrecognized at the time.
- Perucca's reputation was tarnished in 1941 when he was labeled a coward for not supervising Primo Levi's research due to oppressive race laws, but he was actually opposed to the fascist regime.
