N-doped carbon materials are typically prepared and deposited on solid conductive supports, which can sometimes involve time-consuming, complex, and\/or costly procedures. Here, nitrogen-doped screen-printed carbon electrodes (N-SPCEs) were fabricated directly from a lab-formulated ink composed of graphite that was modified with surface nitrogen groups by a simple soft nitriding technique. N-SPCEs prepared from inexpensive starting materials (graphite powder and urea) demonstrated good electrocatalytic activity towards hydrogen peroxide reduction. Amperometric detection of H2O2 using N-SPCEs with an applied potential of \u22120.4 V (vs. Ag\/AgCl) exhibited good reproducibility and stability as well as a reasonable limit of detection (2.5 \u00b5M) and wide linear range (0.020 to 5.3 mM).<\/jats:p>","DOI":"10.3390\/s19173741","type":"journal-article","created":{"date-parts":[[2019,8,29]],"date-time":"2019-08-29T11:26:22Z","timestamp":1567077982000},"page":"3741","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Screen-Printed Soft-Nitrided Carbon Electrodes for Detection of Hydrogen Peroxide"],"prefix":"10.3390","volume":"19","author":[{"given":"Chidiebere I.","family":"Ogbu","sequence":"first","affiliation":[{"name":"Department of Chemistry, East Tennessee State University, Johnson City, TN 37614, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1945-1605","authenticated-orcid":false,"given":"Xu","family":"Feng","sequence":"additional","affiliation":[{"name":"Surface Analysis Laboratory, Department of Chemistry, Virginia Polytechnic Institute and State University, Blacksburg, VA 24061, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samson N.","family":"Dada","sequence":"additional","affiliation":[{"name":"Department of Chemistry, East Tennessee State University, Johnson City, TN 37614, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5534-4319","authenticated-orcid":false,"given":"Gregory W.","family":"Bishop","sequence":"additional","affiliation":[{"name":"Department of Chemistry, East Tennessee State University, Johnson City, TN 37614, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2071","DOI":"10.1016\/j.bios.2006.09.011","article-title":"Design and Development of a Highly Stable Hydrogen Peroxide Biosensor on Screen Printed Carbon Electrode on Horseradish Peroxidase Bound with Gold Nanoparticles in the Matrix of Chitosan","volume":"22","author":"Tangkuaram","year":"2007","journal-title":"Biosens.
