Although great progress has been made in the synthesis of shaped PtM catalysts toward MOR, enhancing the catalytic performance of the PtM to enable it to be commercialized is still a hotspot. In this work, the Au-doped PtNi dendritic nanoparticles (Au-PtNi DNPs) were obtained by doping a small amount of gold (Au) into initially prepared PtNi DNPs, greatly improving their MOR catalytic activity and durability. The energy-dispersive X-ray spectroscopy mapping (EDXS) indicates that the surface of DNPs is mainly composed of Au dopant and PtNi, while the core is mainly Pt, indicating the formation of Au-doped PtNi\/Pt core-shell-like DNP structures. The electrocatalytic performance of the prepared Au-PtNi DNPs with different compositions for the MOR was evaluated using cyclic voltammetry, chronoamperometry, and CO-stripping tests. The experimental findings indicate that the Au-PtNi DNPs showed better MOR performance in comparison with PtNi DNPs and commercial Pt catalysts. Among all the catalysts, 6% Au-PtNi DNPs showed 4.3 times improved mass catalytic activity for the MOR in comparison with commercial Pt catalysts. In addition, all the prepared Au-PtNi DNPs display a remarkable CO tolerance compared to that of PtNi DNPs and commercial Pt catalysts. The dendritic structure of Au-PtNi DNPs can effectively enhance catalytic performance, combined with the electronic effect of Au, Pt, and Ni.<\/jats:p>","DOI":"10.3390\/nano13212855","type":"journal-article","created":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T09:27:28Z","timestamp":1698658048000},"page":"2855","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Au Doping PtNi Nanodendrites for Enhanced Electrocatalytic Methanol Oxidation Reaction"],"prefix":"10.3390","volume":"13","author":[{"given":"Shan","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory for Molecular Genetic Mechanisms and Intervention Research on High Altitude Disease of Tibet Autonomous Region, School of Medicine, Xizang Minzu University, No. 6 East Wenhui Road, Xianyang 712082, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lifeng","family":"Ma","sequence":"additional","affiliation":[{"name":"Key Laboratory for Molecular Genetic Mechanisms and Intervention Research on High Altitude Disease of Tibet Autonomous Region, School of Medicine, Xizang Minzu University, No. 6 East Wenhui Road, Xianyang 712082, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Song","sequence":"additional","affiliation":[{"name":"Key Laboratory for Molecular Genetic Mechanisms and Intervention Research on High Altitude Disease of Tibet Autonomous Region, School of Medicine, Xizang Minzu University, No. 6 East Wenhui Road, Xianyang 712082, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengchun","family":"Yang","sequence":"additional","affiliation":[{"name":"Ministry of Education Key Laboratory for Non-Equilibrium Synthesis and Modulation of Condensed Matter, Key Laboratory of Shaanxi for Advanced Materials and Mesoscopic Physics, State Key Laboratory for Mechanical Behavior of Materials, School of Physics, Xi\u2019an Jiaotong University, No. 28 West Xianning Road, Xi\u2019an 710049, China"},{"name":"National Innovation Platform (Center) for Industry-Education Integration of Energy Storage Technology, Xi\u2019an Jiaotong University, No. 28 West Xianning Road, Xi\u2019an 710049, China"},{"name":"Shaanxi Collaborative Innovation Center for Hydrogen Fuel Cell Performance Improvement, Xi\u2019an Jiaotong University, No. 28 West Xianning Road, Xi\u2019an 710049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"361","DOI":"10.1038\/s41586-021-03482-7","article-title":"Designing the Next Generation of Proton-Exchange Membrane Fuel Cells","volume":"595","author":"Jiao","year":"2021","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"26554","DOI":"10.1021\/acsami.3c01140","article-title":"Alloying with Mn Enhances the Activity and Durability of the CoPt Catalyst toward the Methanol Oxidation Reaction","volume":"15","author":"Deshpande","year":"2023","journal-title":"ACS Appl.
