摘要

Abstract > The traditional luminol–H <sub>2</sub> O <sub>2</sub> electrochemiluminescence (ECL) sensing platform suffers from self‐decomposition of H <sub>2</sub> O <sub>2</sub> at room temperature, hampering its application for quantitative analysis. In this work, for the first time we employ iron single‐atom catalysts (Fe‐N‐C SACs) as an advanced co‐reactant accelerator to directly reduce the dissolved oxygen (O <sub>2</sub> ) to reactive oxygen species (ROS). Owing to the unique electronic structure and catalytic activity of Fe‐N‐C SACs, large amounts of ROS are efficiently produced, which then react with the luminol anion radical and significantly amplify the luminol ECL emission. Under the optimum conditions, a Fe‐N‐C SACs–luminol ECL sensor for antioxidant capacity measurement was developed with a good linear range from 0.8?μ <sc>m</sc> to 1.0?m <sc>m</sc> of Trolox. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“Main”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 传统的Luminol-h <sub> 2 </ sub> O. <sub> 2 </ sub> 电化学发光（ECL）传感平台患有H的自我分解 <sub> 2 </ sub> O. <sub> 2 </ sub> 在室温下，妨碍其用于定量分析的应用。在这项工作中，首次使用铁单原子催化剂（Fe-N-C SACS）作为先进的共反应物促进剂，直接减少溶解的氧气（O. <sub> 2 </ sub> ）反应性氧（ROS）。由于Fe-N-C SACS的独特电子结构和催化活性，有效地产生了大量的RO，然后与鲁米诺的阴离子自由基反应并显着放大鲁米诺ECL排放。在最佳条件下，用于抗氧化能力测量的Fe-N-C Sacs-Luminol ECL传感器，良好的线性范围为0.8ΩμS <sc> m </ sc> 到1.0？m <sc> m </ sc> 拖车。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-19011/'>《Angewandte Chemie》</a> <b style="margin: 0 2px;">|</b><span>2020年第9期</span><b style="margin: 0 2px;">|</b><span>共5页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Gu Wenling&option=202" target="_blank" rel="nofollow">Gu Wenling;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Wang Hengjia&option=202" target="_blank" rel="nofollow">Wang Hengjia;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Jiao Lei&option=202" target="_blank" rel="nofollow">Jiao Lei;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Wu Yu&option=202" target="_blank" rel="nofollow">Wu Yu;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Chen Yuxin&option=202" target="_blank" rel="nofollow">Chen Yuxin;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hu Liuyong&option=202" target="_blank" rel="nofollow">Hu Liuyong;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Gong Jingming&option=202" target="_blank" rel="nofollow">Gong Jingming;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Du Dan&option=202" target="_blank" rel="nofollow">Du Dan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zhu Chengzhou&option=202" target="_blank" rel="nofollow">Zhu Chengzhou;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Key Laboratory of Pesticide and Chemical Biology of Ministry of EducationCentral China Normal UniversityWuhan 430079 P.
