  • Single-atom tailoring of platinum nanocatalysts for high-performance multifunctional electrocatalysis
    Patent number: 12255339
    Abstract: Provided herein are catalyst materials comprising a catalyst support; and PtM? nanowires affixed to the catalyst support, wherein the PtM? nanowires include single atomic species of M? at exterior surfaces of the PtM? nanowires, and M? represents at least one metal, e.g., a metal different from Pt. Also disclosed are manufacturing methods comprising: providing initial MM? nanowires having an initial molar ratio of M:M?, wherein M is a noble metal, and M? is a metal different from M; subjecting the initial MM? nanowires to electrochemical dealloying to partially remove M? and form partially dealloyed MM? nanowires having a subsequent molar ratio of M:M?, wherein the subsequent molar ratio of M:M? is greater than the initial molar ratio of M:M?; and affixing the partially dealloyed MM? nanowires to a catalyst support.
