摘要

Abstract > Monitoring of nitrite is needed for the management of nitrite contamination and to ensure the welfare of environment and human health. Hence, it is important to develop high‐performance sensors that precisely measure nitrite concentration. Herein, the fabrication of a highly sensitive nonenzymatic nitrite sensor based on Fe <sub>2</sub> O <sub>3</sub> nanoparticle coated ZnO nanorods (Fe <sub>2</sub> O <sub>3</sub> NP coated ZnO NRs) is demonstrated. The ZnO NRs are grown on a seeded silver electrode by a hydrothermal method and then coated under optimized conditions with Fe <sub>2</sub> O <sub>3</sub> NPs using a dip‐coating method. Detailed material characterizations and sensor fabrication process are reported. The electrochemical properties of a fabricated nonenzymatic nitrite sensor are tested with different concentrations of nitrite, which indicates that the coating of ZnO NRs with Fe <sub>2</sub> O <sub>3</sub> NPs significantly enhances the electrocatalytic activity. The sensor responds linearly with increasing concentration of nitrite from 1 to 1250 × 10 ?6 <sc>m</sc> with a high sensitivity (131.2 μA μM ?1 cm ?2 ) and low detection limit (0.015 × 10 ?6 <sc>m</sc> ). Moreover, excellent selectivity, stability, and reproducibility allow using these sensors for the determination of nitrite concentration in water with satisfactory results. </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> > 亚硝酸盐污染需要监测亚硝酸盐，并确保环境与人类健康福利。因此，开发精确测量亚硝酸盐浓度的高性能传感器是很重要的。这里，基于Fe的高敏感的非酶亚硝酸盐传感器的制备 <sub> 2 </ sub> O. <sub> 3 </ sub> 纳米粒子涂层ZnO纳米棒（Fe <sub> 2 </ sub> O. <sub> 3 </ sub> 展示了NP涂层ZnO NRS。通过水热法在种子银电极上生长ZnO NR，然后在用Fe的优化条件下涂覆 <sub> 2 </ sub> O. <sub> 3 </ sub> 使用浸涂法的NPS。报道了详细的材料表征和传感器制造过程。用不同浓度的亚硝酸盐测试制造的非酶亚硝酸盐传感器的电化学性质，这表明用Fe涂覆ZnO NRS <sub> 2 </ sub> O. <sub> 3 </ sub> NPS显着增强了电催化活性。传感器随着1至1250×10的亚硝酸盐的浓度越来越高，响应线性响应？6 </ sup> <sc> m </ sc> 具有高灵敏度（131.2μAμm ？1 </ sup> 厘米？2 </ sup> ）和低检测限（0.015×10 ？6 </ sup> <sc> m </ sc> ）。此外，优异的选择性，稳定性和再现性允许使用这些传感器来测定水中的亚硝酸盐浓度，结果令人满意。 </ 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-18063/'>《Advanced materials interfaces》</a> <b style="margin: 0 2px;">|</b><span>2017年第22期</span><b style="margin: 0 2px;">|</b><span>共9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=Ahmad Rafiq&option=202" target="_blank" rel="nofollow">Ahmad Rafiq;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ahn Min‐Sang&option=202" target="_blank" rel="nofollow">Ahn Min‐Sang;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Hahn Yoon‐Bong&option=202" target="_blank" rel="nofollow">Hahn Yoon‐Bong;</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>School of Semiconductor and Chemical EngineeringChonbuk National University567 Baekjedaero Deokjin‐gu Jeonju‐si Jeollabuk‐do 54896 Republic of Korea;</p> <p>School of Semiconductor and Chemical EngineeringChonbuk National University567 Baekjedaero Deokjin‐gu Jeonju‐si Jeollabuk‐do 54896 Republic of Korea;</p> <p>School of Semiconductor and Chemical EngineeringChonbuk National University567 Baekjedaero Deokjin‐gu Jeonju‐si Jeollabuk‐do 54896 Republic of Korea;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/6960.html" title="特种结构材料">特种结构材料;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Fe 2 O 3 nanoparticles&option=203" rel="nofollow">Fe 2 O 3 nanoparticles;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=high sensitivity&option=203" rel="nofollow">high sensitivity;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=nitrite sensors&option=203" rel="nofollow">nitrite sensors;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=nonenzymatic&option=203" rel="nofollow">nonenzymatic;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=ZnO&option=203" rel="nofollow">ZnO;</a> </p> <div class="translation"> 机译：Fe 2 O 3纳米粒子;高灵敏度;亚硝酸盐传感器;非酶;ZnO;
