Herein, PdNi heterostructures with controlled elemental distributions were constructed via a seeded growth strategy. Partially coated Ni islands in the Pd-Ni nanowire and strained Pd branches in the Pd-NiPd nanowires are revealed, respectively. Impressively, Pd-NiPd nanowires with abundant branches exhibit a superior mass current density and cycling stability toward an ethanol oxidation reaction (EOR) and ethylene glycol oxidation reaction (EGOR). The highest mass activities of 8.63 A mgPd\u22121 and 12.53 A mgPd\u22121 for EOR and EGOR, respectively, are realized on the Pd-NiPd nanowires. Theoretical calculations indicate that the Pd (100)-PdNi (111) interface stands out as an active site for enhancing OH adsorption and the decreasing CO bonding interaction. This study not only puts forward a simple method to construct bimetallic nanostructures with desired elemental distributions and interfaces but also demonstrates the significance of interface engineering in regulating the catalytic activity of metallic nanomaterials.<\/jats:p>","DOI":"10.3390\/nano15131047","type":"journal-article","created":{"date-parts":[[2025,7,7]],"date-time":"2025-07-07T02:53:07Z","timestamp":1751856787000},"page":"1047","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Interface Design in Bimetallic PdNi Nanowires for Boosting Alcohol Oxidation Performances"],"prefix":"10.3390","volume":"15","author":[{"given":"Zhen","family":"He","sequence":"first","affiliation":[{"name":"Key Laboratory of Materials Physics, Anhui Key Laboratory of Nanomaterials and Nanotechnology, CAS Center for Excellence in Nanoscience, Institute of Solid State Physics, Hefei Institutes of Physics Science, Chinese Academy of Sciences, Hefei 230031, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4369-2230","authenticated-orcid":false,"given":"Huangxu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Applied Physics, The Hong Kong Polytechnic University, Hung Hom, Kowloon 999077, Hong Kong SAR, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5472-4846","authenticated-orcid":false,"given":"Lingwen","family":"Liao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Materials Physics, Anhui Key Laboratory of Nanomaterials and Nanotechnology, CAS Center for Excellence in Nanoscience, Institute of Solid State Physics, Hefei Institutes of Physics Science, Chinese Academy of Sciences, Hefei 230031, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"14428","DOI":"10.1021\/acscatal.1c04424","article-title":"Fine-tuning the electronic structure of dealloyed PtCu nanowires for efficient methanol oxidation reaction","volume":"11","author":"Wang","year":"2021","journal-title":"ACS Catal."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"7985","DOI":"10.1021\/ja402072r","article-title":"Surface composition tuning of Au\u2013Pt bimetallic nanoparticles for enhanced carbon monoxide and methanol electro-oxidation","volume":"135","author":"Suntivich","year":"2013","journal-title":"J.
