Model catalysts for the nitrate reduction reaction were obtained by electrodeposition of metal Co, Fe, and bimetallic Fe\/Co nanoparticles from aqueous solutions onto a graphite substrate. The samples were characterized by the following methods: SEM, XRD, XPS, UV\u2013vis spectroscopy, cyclic (and linear) voltammetry, chronoamperometry, and electrochemical impedance spectroscopy. In addition, the determination of the electrochemically active surface was also performed for all electrocatalysts. The best electrocatalyst was a sample containing Fe-nanoparticles on the layer of Co-nanoparticles, which showed a Faradaic efficiency of 58.2% (E = \u22120.785 V vs. RHE) at an ammonia yield rate of 14.6 \u03bcmol h\u22121 cm\u22122 (at ambient condition). An opinion was expressed to elucidate the mechanism of coordinated electrocatalytic action of a bimetallic electrocatalyst. This work can serve primarily as a starting point for future investigations on electrocatalytic conversion reactions to ammonia using model catalysts of the proposed type.<\/jats:p>","DOI":"10.3390\/ijms25137089","type":"journal-article","created":{"date-parts":[[2024,6,28]],"date-time":"2024-06-28T03:42:30Z","timestamp":1719546150000},"page":"7089","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Enhancing Efficiency of Nitrate Reduction to Ammonia by Fe and Co Nanoparticle-Based Bimetallic Electrocatalyst"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8399-6821","authenticated-orcid":false,"given":"Irina","family":"Kuznetsova","sequence":"first","affiliation":[{"name":"Department of Chemistry, Lomonosov Moscow State University, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2333-660X","authenticated-orcid":false,"given":"Olga","family":"Lebedeva","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Lomonosov Moscow State University, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5866-5510","authenticated-orcid":false,"given":"Dmitry","family":"Kultin","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Lomonosov Moscow State University, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5760-1796","authenticated-orcid":false,"given":"Mikhail","family":"Mashkin","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Lomonosov Moscow State University, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantin","family":"Kalmykov","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Lomonosov Moscow State University, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonid","family":"Kustov","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Lomonosov Moscow State University, Moscow 119991, Russia"},{"name":"N.D.
