In this paper, PtPd\/Nafion\/GCE is prepared by electrochemical cyclic voltammetry deposition method based on electrodepositing nanostructured platinum (Pt)-palladium (Pd) nanoparticles in Nafion film-coated glassy carbon electrode (GCE). The influence of deposition parameters and chemical composition (atomic ratio of Pt and Pd) on the electrochemical behaviour of PtPd\/Nafion\/GCE has been investigated. PtPd\/Nafion\/GCE displays a remarked electrocatalytic activity for the oxidation of FA and exhibits a linear relationship in the range of 10\u20135000 <jats:italic>\u03bc<\/jats:italic>M, with a detection limit of 3.3 <jats:italic>\u03bc<\/jats:italic>M in 0.1 M H<jats:sub>2<\/jats:sub>SO<jats:sub>4<\/jats:sub> solution. It is proved that the detection performance of PtPd\/Nafion\/GCE electrode is valuable for further application with low detection limit, wide linear range, favourable selectivity and high response.<\/jats:p>","DOI":"10.1088\/1361-6528\/ad0124","type":"journal-article","created":{"date-parts":[[2023,10,7]],"date-time":"2023-10-07T22:23:59Z","timestamp":1696717439000},"page":"025704","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Efficient formaldehyde sensor based on PtPd nanoparticles-loaded nafion-modified electrodes"],"prefix":"10.1088","volume":"35","author":[{"given":"Shuting","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4421-7696","authenticated-orcid":true,"given":"Li","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowei","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wentao","family":"Ju","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxia","family":"Liang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhu","family":"Tao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yumeng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benfeng","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoying","family":"Wei","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2023,10,26]]},"reference":[{"key":"nanoad0124bib1","doi-asserted-by":"publisher","first-page":"181","DOI":"10.1177\/0192623312466459","article-title":"Formaldehyde carcinogenicity research","volume":"41","author":"Swenberg","year":"2012","journal-title":"Toxicol.
