Moreover, H2O2 is also an energetic material used as fuel, with specific attention given to its safety. Therefore, it is of great importance to explore and prepare good sensitive materials for the detection of H2O2 with a low detection limit and high selectivity. In this work, a kind of hydrogen peroxide electrochemical sensor has been fabricated. That is, polypyrrole (PPy) has been electropolymerized on the glass carbon electrode (GCE), and then Ag and Cu nanoparticles are modified together on the surface of polypyrrole by electrodeposition. SEM analysis shows that Cu and Ag nanoparticles are uniformly deposited on the surface of PPy. Electrochemical characterization results display that the sensor has a good response to H2O2 with two linear intervals. The first linear range is 0.1\u20131 mM (R2 = 0.9978, S = 265.06 \u03bcA\/ (mM \u00d7 cm2)), and the detection limit is 0.027 \u03bcM (S\/N = 3). The second linear range is 1\u201335 mM (R2 = 0.9969, 445.78 \u03bcA\/ (mM \u00d7 cm2)), corresponding to 0.063 \u03bcM of detection limit (S\/N = 3). The sensor reveals good reproducibility (\u03c3 = 2.104), repeatability (\u03c3 = 2.027), anti-interference, and stability. The recoveries of the electrode are 99.84\u2013103.00% (for 0.1\u20131 mM of linear range) and 98.65\u2013104.80% (for 1\u201335 mM linear range). Furthermore, the costs of the hydrogen peroxide electrochemical sensor proposed in this work are reduced largely by using non-precious metals without degradation of the sensing performance of H2O2. This study provides a facile way to develop nanocomposite electrochemical sensors.<\/jats:p>","DOI":"10.3390\/s23208536","type":"journal-article","created":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T10:36:56Z","timestamp":1697625416000},"page":"8536","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Hydrogen Peroxide Electrochemical Sensor Based on Ag\/Cu Bimetallic Nanoparticles Modified on Polypyrrole"],"prefix":"10.3390","volume":"23","author":[{"given":"Yanxun","family":"Guan","sequence":"first","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"},{"name":"School of Electronic Engineering and Automation, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2900-1325","authenticated-orcid":false,"given":"Fen","family":"Xu","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4684-683X","authenticated-orcid":false,"given":"Lixian","family":"Sun","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Yumei","family":"Luo","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Riguang","family":"Cheng","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9012-2639","authenticated-orcid":false,"given":"Yongjin","family":"Zou","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Lumin","family":"Liao","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Information Materials & Guangxi Collaborative Innovation Center for Structure and Properties for New Energy and Materials, School of Material Science and Engineering, Guilin University of Electronic Technology, Guilin 541004, China"},{"name":"School of Electronic Engineering and Automation, Guilin University of Electronic Technology, Guilin 541004, China"}]},{"given":"Zhong","family":"Cao","sequence":"additional","affiliation":[{"name":"Hunan Provincial Key Laboratory of Materials Protection for Electric Power and Transportation, Changsha University of Science & Technology, Changsha 410114, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"386","DOI":"10.1016\/j.jpba.2015.01.018","article-title":"High-Performance Liquid Chromatography Method for the Determination of Hydrogen Peroxide Present or Released on Teeth Bleaching Kits and Hair Cosmetic Products","volume":"107","author":"Gimeno","year":"2015","journal-title":"J.
