Electrochemical studies reveal that the stripping of bulk Cu can induce underpotential deposition (UPD) of Pb during the galvanic replacement reaction (GRR) process, which affects the composition and morphology of Pb-containing Pd\u2013Au nanoparticles. The electrocatalytic activity of Pb-containing nanoparticles toward formaldehyde oxidation was examined in an alkaline solution, and the experimental results showed that formaldehyde mainly caused direct oxidation on the surface of Pb-containing Pd\u2013Au nanoparticles while inhibiting the formation of CO poison to a large degree. The proposed formaldehyde sensor exhibits a linear amperometric response to formaldehyde concentrations from 0.01 mM to 5.0 mM, with a sensitivity of 666 \u03bcA mM\u22121 cm\u22122, a limit of detection (LOD) of 0.89 \u03bcM at triple signal-to-noise, rapid response, high anti-interference ability, and good repeatability.<\/jats:p>","DOI":"10.3390\/molecules29122772","type":"journal-article","created":{"date-parts":[[2024,6,11]],"date-time":"2024-06-11T11:58:58Z","timestamp":1718107138000},"page":"2772","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Double-Cabin Galvanic Cell-Synthesizing Nanoporous, Flower-like, Pb-Containing Pd\u2013Au Nanoparticles for Nonenzymatic Formaldehyde Sensor"],"prefix":"10.3390","volume":"29","author":[{"given":"Zhao","family":"Huang","sequence":"first","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"},{"name":"Key Laboratory of Chemical Biology and Traditional Chinese Medicine Research (Ministry of Education of China), College of Chemistry and Chemical Engineering, Hunan Normal University, Changsha 410081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongsen","family":"Tang","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0767-5997","authenticated-orcid":false,"given":"Long","family":"Chao","sequence":"additional","affiliation":[{"name":"Hunan Key Laboratory of Biomedical Nanomaterials and Devices, College of Life Sciences and Chemistry, Hunan University of Technology, Zhuzhou 412007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111982","DOI":"10.1016\/j.jece.2024.111982","article-title":"Efficient removal of formaldehyde from wastewater by Cu defect induction of dendritic snowflake Cu7S4 Fenton-like catalysts","volume":"12","author":"Wu","year":"2024","journal-title":"J.
