The cover art is attributed to an article entitled “Structural Control of PtNi Catalysts through Precise Synthesis Conditions and Elucidation of Property Determinants by operando XAS Analysis” by Weijie Cao et al. Editor’s Choice of this issue is a comprehensive investigation of the PtNi alloy nanowire as an efficient oxygen reduction reaction (ORR) catalyst.
Precise controlling in the shape of Pt-based alloy catalysts is an effective approach to enhance their catalytic ORR activity for proton exchange membrane fuel cell applications. In this study, the authors developed a standardized synthesis method for PtNi-alloy nanowire (NW) with outstanding ORR activity. Morphological observation combined with operando X-ray absorption spectroscopic analysis on the PtNi-alloy NWs revealed that surface roughness, high-index facet exposure, and electronic state of Pt under electrochemical conditions jointly contribute to the catalytic activity and durability.
