A Biofuel Cell Based on Biocatalytic Reactions of Lactate on Both Anode and Cathode Electrodes – Extracting Electrical Power from Human Sweat

Koushanpour Ashkan; Gamella Maria; Katz Evgeny

摘要

Abstract > Electrodes composed of carbon fibers were modified with graphene nano‐sheets in order to increase their surface area and facilitate electrochemical reactions. Electrocatalytic species, such as Meldola's blue (MB) and hemin were immobilized on the graphene surface due to their π‐π stacking and then used for electrocatalytic oxidation of NADH and reduction of H <sub>2</sub> O <sub>2</sub> , respectively. Further modification of these electrodes with enzymes producing NADH and H <sub>2</sub> O <sub>2</sub> in?situ (lactate dehydrogenase, LDH, and lactate oxidase, LOx, respectively), allowed assembling of a biofuel cell operating in the presence of lactate, oxygen and NAD + . The cathode of the biofuel cell required lactate and O <sub>2</sub> for its operation, while the anode operated in the presence of lactate and NAD + . Notably, both bioelectrocatalytic electrodes operated in the presence of lactate, one producing H <sub>2</sub> O <sub>2</sub> in the reaction catalyzed by LOx in the presence of O <sub>2</sub> , second producing NADH in the reaction catalyzed by LDH in the presence of NAD + . Both reactions were performed in the biofuel cell without separation of the cathodic and anodic solutions and with no need of a membrane. The biofuel cell was tested in solutions mimicking human sweat and then in real human sweat samples, demonstrating substantial power release being able to activate electronic devices. </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 XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>抽象</ title> >电极组成用石墨烯纳米片改性碳纤维以增加它们的表面积并促进电化学反应。由于其π-π堆叠，在石墨烯表面上固定在石墨烯表面上的电催化物质，然后用于NADH的电催化氧化和H <sub> 2 </ sub> O <sub> 2的电催化氧化</ sub>分别。进一步修饰这些电极，用酶产生NADH和H <sub> 2 </ sub> O中的α原位（乳酸脱氢酶，LDH和乳酸氧化酶，LOX），允许组装生物燃料细胞在存在乳酸，氧和NAD + </ sup>的存在下操作。生物燃料电池的阴极需要乳酸和O <sub> 2 </ sub>的操作，而阳极在乳酸和NAD + </ sup>的存在下操作。值得注意的是，在乳酸乳酸存在下，两种生物电催化电极都在乳酸存在下操作，在O <sub> 2 <sub的存在下在LOx催化的反应中产生H <sub> 2℃。 >，在NAD + </ sup>存在下通过LDH催化的反应中的第二种产生NADH。在生物燃料电池中进行两种反应，无需分离阴极和阳极溶液并且不需要膜。在模拟人类汗液中的溶液中测试生物燃料电池，然后在真正的人类汗液中进行测试，证明了能够激活电子器件的大量电力释放。 </ p> </ abstract> </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-22546/'>《Electroanalysis 》</a> <b style="margin: 0 2px;">|</b><span>2017年第6期</span><b style="margin: 0 2px;">|</b> <span>共10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=Koushanpour Ashkan&option=202" target="_blank" rel="nofollow">Koushanpour Ashkan;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Gamella Maria&option=202" target="_blank" rel="nofollow">Gamella Maria;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Katz Evgeny&option=202" target="_blank" rel="nofollow">Katz Evgeny;</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>Department of Chemistry and Biomolecular ScienceClarkson UniversityPotsdam NY 13699-5810 USA;</p> <p>Department of Chemistry and Biomolecular ScienceClarkson UniversityPotsdam NY 13699-5810 USA;</p> <p>Department of Chemistry and Biomolecular ScienceClarkson UniversityPotsdam NY 13699-5810 USA;</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/4817.html" title="电化学、电解、磁化学">电化学、电解、磁化学 ;</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=Biofuel cell&option=203" rel="nofollow">Biofuel cell;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sweat&option=203" rel="nofollow">Sweat;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Modified electrode&option=203" rel="nofollow">Modified electrode;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Graphene&option=203" rel="nofollow">Graphene;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lactate oxidase&option=203" rel="nofollow">Lactate oxidase;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lactate dehydrogenase&option=203" rel="nofollow">Lactate dehydrogenase;</a> </p> <div class="translation"> 机译：生物燃料细胞;汗;改性电极;石墨烯;乳酸氧化酶;乳酸脱氢酶;
